Significant events in computing include events relating directly or indirectly to software, hardware and wetware. Excluded (except in instances of significant functional overlap) are:

• events in general robotics
• events about uses of computational tools in biotechnology and similar fields (except for improvements to the underlying computational tools) as well as events in media-psychology except when those are directly linked to computational tools

Currently excluded are:

• events in computer insecurity/hacking incidents/breaches/Internet conflicts/malware if they are not also about milestones towards computer security
• events about quantum computing and communication
• economic events and events of new technology policy beyond standardization

• An AI-based study shows for the first time that fingerprints from different fingers of the same person share strong detectable similarities.^[1][2]
• A preprint trial suggests large language models could be used for tailored manipulation, being more persuasive than humans when using personal information.^[3][4]

• Notable innovations: LAION releases a first version of BUD-E, a fully open source voice assistant,^[5] an automatic waste sorting system that can distinguish between over 500 waste categories is released,^[6] researchers describe an AI ecosystem interface of foundation models connected to many APIs as specialized subtask-solvers,^[7] the chatbot Grok is made open source to a substantial extent.^[8][9]

• Researchers describe an approach for an optical disk with petabit capacity,^[10][11]

• Chatbot and text-generating AI, ChatGPT (released on 30 Nov 2022), a large language model, became popular, with some considering the large public's attention as unwarranted hype as potential applications are limited. Similar software such as Cleverbot existed for many years, and the software is, on the fundamental level, not structured toward accuracy – e.g. providing seemingly credible but incorrect answers to queries and operating "without a contextual understanding of the language" – but only toward essentially the authenticity of mimicked human language.^{[13][14][15][16][17]} It was estimated that only two months after its launch, it had 100 million active users.^[18] Applications may include solving or supporting school writing assignments,^[19] malicious social bots (e.g. for misinformation, propaganda, and scams),^[20][21] and providing inspiration (e.g. for artistic writing or in design or ideation in general).^[22][23]

• Google released chatbot Bard due to effects of the ChatGPT release,^[24] with potential for integration into its Web search and, like ChatGPT software, also as a software development helper tool.^[25] DuckDuckGo released the DuckAssist feature integrated into its search engine that summarizes information from Wikipedia to answer search queries that are questions. The experimental feature was shut down without explanation on 12 April.^[26][27][28] There has been further development regarding LLMs or ChatGPT as user interfaces of Wikipedia or as software using its structured knowledge by others.^[29][30] A proprietary feature by scite.ai was released that delivered answers that use research papers and provide citations for the quoted paper(s). It may demonstrate an alternative approach to ChatGPT whose fundamental algorithms are not designed to generate text that is true, including for example "hallucinations" and fake citations or misinformation more generally.^[31][32] Elicit.org may provide a free alternative to this tool.^[33][34] A broader alternative approach to the software's Q&A applications and use of text generation for assignments may be the improvement of media literacy and Web search skills in education systems.

• Further LLM developments during what has been called an "AI boom" included: local or open source versions of LLaMA which was leaked in March,^[35][36][37] news outlets reported on GPT4-based Auto-GPT that given natural language commands uses the Internet and other tools in attempts to understand and achieve its tasks with unclear or so-far little practicality,^[38] a systematic evaluation of answers from four "generative search engines" suggested their outputs "appear informative, but frequently contain unsupported statements and inaccurate citations",^[39] a multi-modal open source tool for understanding and generating speech,^[40] a data scientist argued that "researchers need to collaborate to develop open-source LLMs that are transparent" and independent,^[41] Stability AI launched an open source LLM.^[42]

• A method for editing NeRF scenes, a novel media technique from 2020,^[43] with natural language commands was demonstrated by Nvidia.^[44][45]
• An open letter "Pause Giant AI Experiments" initiated by the Future of Life Institute called for "AI labs to immediately pause for at least 6 months the training of AI systems more powerful than GPT-4" due to "profound risks to society and humanity".^[46][47] It received substantial media attention and also contributed to speculations about perceived large LLM potential). At the time there was extensive media coverage of views that regard ChatGPT as a potential step towards AGI or sentient machines, also extending to some academic works (e.g. a popular preprint by a company).^[12] The coverage focused on such views may not represent the majority expert views and, for example, some researchers noted that e.g. the ability to generate coherent text and imitations are not the same as understanding language.^[48] A set of techniques under development included self-refining code or text.^[49]
• ChatGPT was shown to outperform human doctors in responding to online medical questions when measured on quality and empathy by "a team of licensed health care professionals",^[50][51] albeit the chatbot may have previously been trained with these reddit question and answers threads.
• News outlets reported on a preprint that described the development of a large language model software that can answer medical questions with a 67.6% accuracy on MedQA and nearly matched human clinician performance when answering open-ended medical questions, Med-PaLM. The AI makes use of comprehension-, recall of knowledge-, and medical reasoning-algorithms but remains inferior to clinicians.^[52][53][54] As of 2023, humans often – if not most often – conduct query-based web searches, read websites and/or conduct physical doctor's visits to inquire health information, despite various difficulties,^{[55][56][57][58]} partly as they typically did not undergo any formal training in media literacy,^[59] digital literacy^[60][61] or health literacy,^[62] as such is not part of schools curricula in most education systems as of 2023.^[62][59][60]
• A novel potentially significantly more efficient text-to-image approach, as implemented in MUSE, was reported.^[63][64]
• A first successful autonomous long-duration operation, including simulated combat, of a modified F-16 fighter jet, X-62A, by two AI software was reported.^[65][66][67]
• A text-to-speech synthesizer, VALL-E, that can be trained to mimic anybody's voice with just three seconds of voice data and may produce the most natural-sounding results to date, was reported in a preprint.^[68][69]
• A use of world models for a wide range of domains that make decisions using e.g. different 3D worlds and reward frequencies and outperforms previous approaches, DreamerV3, was reported as a step towards general artificial intelligence in a preprint.^[70][71]
• A large language model, ProGen, that can generate functional protein sequences with a predictable function, with input including tags specifying protein properties, was reported.^[72][73]
• A deep-learning model, ZFDesign, for zinc finger design for any genomic target for gene- and epigenetic-editing was reported.^[74][75]
• Software for generating 3D dynamic scenes (text-to-4D), MAV3D, was reported.^[76][77]
• A study reported the development of deep learning algorithms to identify technosignature candidates, finding 8 potential alien signals not detected earlier.^[78][79]
• An international norms and arms control proposal for artificial intelligence in the military (such as LAWs and weapons decision-making), the "Political Declaration on Responsible Military Use of Artificial Intelligence and Autonomy]", was published by the U.S. government.^[80][81][82] The first international summit on military AI led to a joint unbinding statement by the U.S., China and other nations, with some external calls for starting negotiations on an internationally binding law or an enforcement-mechanisms-driven law.^[83]
• The world's first COVID-19 drug designed by generative AI was approved for human use, with clinical trials expected to begin in China. The new drug, ISM3312, was developed by Insilico Medicine.^[84]
• The LLM GPT-4 was launched by OpenAI.^[85][86] It and ChatGPT based on it continued to receive major global media attention.
• Researchers suggested that growing influence of industry in AI research means that "public interest alternatives for important AI tools may become increasingly scarce".^[87]
• Google revealed PaLM-E, an embodied multimodal language model with 562 billion parameters.^[88][89]

• Researchers demonstrated an open source 'AI scientist' that can create models of natural phenomena from knowledge axioms and experimental data, showing the software can rediscover physical laws like "Kepler's third law of planetary motion, Einstein's relativistic time-dilation law, and Langmuir's theory of adsorption" using logical reasoning and a few data points.^[91][90]

• Researchers demonstrated a non-invasive brain-reading method. It can translate a person's neural activity into a continuous stream of text using fMRI data and transformer machine learning. Prior training data is required for this semantic decoding. Participants listened to stories for 16 hours while their brain activity was recorded.^[92]
• A new AI algorithm developed by Baidu was shown to boost the antibody response of COVID-19 mRNA vaccines by 128 times.^[93]

• Computational neuroscientists showed that people with higher intelligence scores in HCP cognitive tests took more time to solve difficult problems and that their higher synchrony between brain areas allowed for better integration of evidence (or progress) from preceding working memory sub-problem processing. Reducing synchrony in "avatar" simulations, that were adjusted and tuned towards personalization, "led decision-making circuits to quickly jump to conclusions". Their codified results may be useful for an understanding of cognition to replicate or imitate in bio-inspired computing.^[95][94]
• AI was used to develop an experimental antibiotic called abaucin, which is shown to be effective against A. baumannii.^[96]

• A machine learning model is trained to recognise the key features of chemicals with senolytic activity. It finds three chemicals – ginkgetin, periplocin and oleandrin – able to remove senescent cells without damaging healthy cells.^[97][98]
• Articles in science outlets like Nature suggest contemporary viral concerns about hypothetical existential risk of AI "plays into the tech companies' agenda" – partly in the form of 'criti-hype'^[99] – and that this "hinders effective regulation of the societal harms AI is causing right now" and in the near-future.^[100]
• A science writer provides an overview of "the nascent industry of AI-designed drugs".^[101]

• A preprint introduces the concept of "thought cloning" by which AI use data of or imitate human thinking.^[102]

• Metaresearchers showed that AI trained with study-author-networks data could generate scientifically promising "alien" hypotheses that would likely not be considered otherwise.^[103]
• A study provides an overview and living review of open source LLMs, assessing the levels of openness of their differentiated elements and reviewing the risks of relying on proprietary software or the importance of open source AI.^[104]

• Notable innovations: a low-cost open source air pollution sensor (Flatburn),^[132][133] a laser-using drone-based methane plume localization method,^[134] and a portable EEG helmet with significant accuracy of decoding thought words to text (DeWave).^[135][136]

• Researchers demonstrated how pre-installed apps on Android smartphones in China are used for mass surveillance in China.^[137][138]
• Scientists reviewed safety-by-design technology- and policy-based approaches to ensure biosafety and biosecurity to prevent engineered pathogen pandemics, including digital methods such as DNA sequence screening, some of which are already implemented and part of regulations to some degree.^{[139][additional citation(s) needed]}
• Studies investigated dating apps, revealing high gender inequality,^[140] partly exploring possible relevance to the rise of both "sexual loneliness" and concentration of sex in various developed countries,^[140] and reported subsets of well-being effects.^{[141][140][142][143]}
• A study hypothesized mental health awareness efforts (in current forms) or glamorised and romanticised mental disorders on social media (e.g. quotes about depression on aesthetically-appealing backgrounds shared widely on certain social media)^[which?] may have contributed to the recent rise in reported mental health problems – by intensifying and over-diagnosing of such – beyond e.g. increased reporting of previously under-recognised symptoms or mental health-related issues.^[144][145]
• A news outlet reported on a systematic study of major issues in popular currently available commercial VPNs for Internet privacy and security.^[146][147]
• Researchers reported 'digital resignation', calling for regulations and education reform.^[148]
• Parts of Twitter's recommender algorithms became open source, welcomed and requested by many albeit with several issues related to code exclusion and verifiability.^{[149][150][151]} Around the time, the free version of its API, which was also used for research, esd shut down^[152] – followed shortly thereafter by reddit,^[153] proprietary verification checkmarks caused controversy,^[154] parts of its source code were leaked,^[155] and applications of a "state-affiliated media" label – which purportedly uses "Category:Publicly funded broadcasters" data which, like the label, does not differentiate and list the shares of funding sources – caused controversy.^[156][157] In April, Twitter was warned by EU digital policy-makers after a report indicated its recent policies "boost" Russian disinformation-based propaganda.^[158]
• One of the first empirical studies on what real users are shown during their typical use of popular Web search engines interpreted its results to show that choices for unreliable news sources for their queries are driven primarily by users' own choices and less by the engine's algorithms. The Web scientists linked their findings to the concept of filter bubbles which emphasizes the role of design-^[159] and personalization algorithms.^[160][161] A report accompanied by an open letter concluded that Alphabet Inc, against its voluntary promises, still runs climate misinformation ads.^[162] Statements by Elon Musk^{[better source needed]} in 2022 suggested YouTube may also show ethically disputed advertising other than science-related misinformation such as extensively showing "scam ads".^{[163][164][165]}

It suggests media literacy programs with tested strategies and solutions for identified search engines issues are needed.^[167]
• The concept of enshittification] about the quality of content on social media platforms introduced in 2022 gained traction.^[168][169]

• Notable innovations: a Tor browser-equivalent Web browser for privacy-protected browsing when using a VPN (Mullvad browser) was demonstrated,^{[170][171][172]} after moderators of the Web content aggregation-based platform Reddit strike against the site's introduction of API pricing and the ensuing closing of several mobile client apps, several novel decentralized open source aggregation platforms gain substantial numbers of users – most notably Lemmy and Kbin which can synchronize their posts via interoperability,^{[173][174][175]} the first upgrade of the Global Earthquake Model data for disaster risk reduction,^[176][177] and the misinformation-countering system Community Notes became relatively widely used on X (formerly Twitter).^[178]

• Scientists coalesced recent developments (see also 2022-12-26) using human brain organoids into a new field they term organoid intelligence (OI), seeking to harness OI for computing – as a novel type of AI – in an ethically responsible way. Networks of such miniature tissues could become functional using stimulus-response training or organoid-computer interfaces – to potentially become "more powerful than silicon-based computing" for a range of tasks – and could also be used for research of various pathophysiologies, brain development, human learning, memory and intelligence, and new therapeutic approaches against brain diseases.^[183][184]

• News outlets reported artificial intelligence art had won the first place in a digital art competition.^[199] Such artistic imagery is generated using input consisting of text and sometimes images, usually including parameters such as artistic style (text-to-image generation). Around the time, an expert concluded that "AI art is everywhere right now", with even experts not knowing what it will mean,^[200] a news outlet established that "AI-generated art booms" and reported issues of copyright and automation of professional artists,^[201] a news outlet investigated how online communities (e.g. their rules) confronted with many such artworks react,^[202] a news outlet raised concerns over deepfakes,^[203] a magazine highlighted possibilities of enabling "new forms of artistic expression",^[204] and an editorial noted that it may be seen as a welcome "augmentation of human capability".^{[205][additional citation(s) needed]} Moreover, additional functionalities – such as enabling the use of user-provided concepts (like an object or a style) learned from few images for novel personalized art generated from the associated word/s^[206] or expanding beyond the borders of artistic images in the same style^[207] – were reported. On 22 August,^[208][209] Stable Diffusion released as open source software, making the technology more accessible and free to use on personal hardware as well as extendable by third-parties (i.e. other software projects).^[209][210]

• [Meta/Policy/Philosophy] – Thomas Metzinger, a German philosopher of cognitive science and applied ethics, called for a "global moratorium on synthetic phenomenology" which, "until 2050", precautionarily bans "all research that directly aims at or knowingly risks the emergence of artificial consciousness on post-biotic carrier systems" – and could be gradually refined. The paper does not describe mechanisms of global enforcement of such proposed regulations which do not consider biotic or semi-biotic systems and aims to limit suffering risks.^[342][343]
• [Type of database] – A new global food emissions database indicated that the current food systems are responsible for one third of the global anthropogenic greenhouse gas emissions.^[344][345]

• GitHub Copilot, a programmer assistant AI, was released.^[370][371] Later FOSS variants of the tool included FauxPilot.^[372]

• In the debate regarding the cognitive impacts of smartphones and digital technology, a group reported that, contrary to widespread belief, scientific evidence does not show that these technologies harm biological cognitive abilities and that they instead change predominant ways of cognition – such as a reduced need to remember facts or conduct mathematical calculations by pen and paper outside contemporary schools. However, some activities – like reading novels – that require long attention-spans and don't feature ongoing rewarding stimulation may become more challenging in general.^[373][374]

• Scientists concluded that personal carbon allowances (PCAs) could be a component of climate change mitigation. They found that the economic recovery from COVID-19 and novel digital technology capacities open a window of opportunity for first implementations. PCAs would consist of – e.g. monetary – credit-feedbacks and decreasing default levels of per capita emissions concessions. The researchers found that recent advances in machine learning technology and "smarter home and transport options make it possible to easily track and manage a large share of individuals' emissions" and that feedback effective in engaging individuals to reduce their energy-related emissions and relevant new personalized apps could be designed.^{[388][389][390]} Issues may include privacy, evaluating emissions from individuals co-running multinational companies and the availability and prices of products and services.

• A study of data traffic by popular smartphones running variants of the Android software found substantial by-default data collection and sharing with no opt-out (i.e. even the NetGuard firewall, which is not installed by default, may not reliably and completely prevent such data traffic) and implications for users' privacy, control and security.^[396][397]
• Media outlets reported novel technologies for virtual try-ons of clothes for more sustainable fashion and improved online shopping, which increased relative to shopping at local shops that store clothes due to the COVID-19 pandemic.^[398][399]
• A method of DNA data storage with 100 times the density of previous techniques was announced.^[400]

• April 20 – Researchers demonstrated a diffusive memristor fabricated from protein nanowires of the bacterium Geobacter sulfurreducens which functions at substantially lower voltages than previously described ones and may allow the construction of artificial neurons which function at voltages of biological action potentials. The nanowires have a range of advantages over silicon nanowires and the memristors may be used to directly process biosensing signals, for neuromorphic computing and/or direct communication with biological neurons.^{[428][429][430]}
• May 22 – Australian computer scientists reported achieving, thus far, the highest internet speed in the world from a single optical chip source over standard optical fiber, amounting to 44.2 Terabits per sec, or "downloading 1000 high definition movies in a split second".^{[431][432][433]}
