AI systems are improving by leaps and bounds. From the early 2022 fumbling release of ChatGPT, which couldn’t correctly count the number of a’s in my name (it claimed two), we reached OpenAI’s release of math papers where an internal AI model solved many hundreds of previously open math problems. Aside from philosophical arguments, practical claims regarding the superiority of human thought, on grounds such as hallucinations or bias, increasingly appear to me like rearguard defence. For the bulk of today’s cognitive work, the writing’s on the wall: AI will take over. https://www.spinellis.gr/blog/20261008 Diomidis Spinellis Text Thinking will become a hobby https://www.spinellis.gr/blog/20261008 2026-10-08T09:42:45-00:00 en https://www.spinellis.gr/blog/20260817 Many prestigious scientific venues have suffered from papers containing hallucinated citations. GPTZero reports finding 100 hallucinations in NeurIPS 2025 accepted papers and 50 hallucinations in ICLR 2026 submissions . Hallucinated citations are references generated by an AI system that appear credible but point to sources that do not exist or do not support the claims attributed to them. They may contain plausible-looking but incorrect authors, titles, journals, dates, DOIs, or URLs, making them difficult to detect without thorough verification. Such citations, justifiably, undermine the confidence in both scientific publications and in the process that produces them. How should the scientific community address this issue? https://www.spinellis.gr/blog/20260817 Diomidis Spinellis Text A controversial proposal for hallucinated references https://www.spinellis.gr/blog/20260817 2026-08-17T15:28:22-00:00 en https://www.spinellis.gr/blog/20260803 A recent Financial Times long-read article outlined how diverse financial institutions try to promote the use of blockchain technology to optimize how their transactions are performed. This will allow them to take place instantly, rather than waiting for clearing, around the clock, rather than during working hours, and with automated actions, such as the rebalancing of a tracker fund when asset prices change. Obviously this entails many risks. Although the article tried to explain the basics of how blockchain technology works, it left out many important elements. Read on to learn the absolute essentials of blockchain technology in fewer than 500 simple words. https://www.spinellis.gr/blog/20260803 Diomidis Spinellis Text Blockchain technology in 500 simple words https://www.spinellis.gr/blog/20260803 2026-08-04T10:27:51-00:00 en https://www.spinellis.gr/blog/20260715 For decades the accepted management wisdom has been for managers to delegate tasks and for organizations to outsource activities that aren’t core to their operations. Yet, when the proposed delegate or supplier is an AI agent, these established practices are suddenly portrayed as irresponsible, dehumanizing, or even immoral. Much of this resistance has all the marks of a moral panic: a novel technology is judged through its most alarming failures, its benefits are discounted, and its use is treated as crossing a boundary rather than as another management decision. Here’s the thing: delegating work to an AI agent is neither inherently wise nor inherently reckless. As with human delegation and organizational outsourcing, what matters is the task, the controls, and who remains accountable. https://www.spinellis.gr/blog/20260715 Diomidis Spinellis Text Barings, Boeing, and Bots https://www.spinellis.gr/blog/20260715 2026-07-15T15:54:20-00:00 en https://www.spinellis.gr/blog/20260708 Over the past few days I changed the way the uutils project’s sed program handles data to default from characters to raw bytes. This improves compatibility with GNU sed and also performance. Given the change’s size and extent (13 changed files, 1740 insertions, 609 deletions), I worked with an AI agent (OpenAI Codex), which allowed me to experience first-hand both its power and limitations. https://www.spinellis.gr/blog/20260708 Diomidis Spinellis Text Why agentic AI needs better experts https://www.spinellis.gr/blog/20260708 2026-07-08T10:30:24-00:00 en https://www.spinellis.gr/blog/20260702 With ever-more program code created through generative AI, it is important to document its provenance. In industry this can help diagnose the root cause of problems discovered long after the code was written, locate issues with a similar cause, and evaluate the cost and benefits of AI. In educational settings it can help students be honest, mindful, reflective, and transparent regarding their use of generative AI and provide educators with data they can use to evaluate objectively student work. In both settings, provenance information can guide a code review’s focus because humans and AI fail in different ways . https://www.spinellis.gr/blog/20260702 Diomidis Spinellis Text Documenting AI-generated code commits https://www.spinellis.gr/blog/20260702 2026-07-08T08:00:37-00:00 en https://www.spinellis.gr/blog/20260523 Here’s the thing: when working on code with GenAI assistance (from a chat-bot, through IDE auto-completion, or, increasingly, with an AI agent) you need a better understanding of the system than when working without. Cognitive psychology and the workings of large language models (LLMs) give us four clues on why this happens. https://www.spinellis.gr/blog/20260523 Diomidis Spinellis Text Why reviewing AI-generated code is devilishly hard https://www.spinellis.gr/blog/20260523 2026-05-23T18:53:28-00:00 en https://www.spinellis.gr/blog/20260413 In a keynote presentation at the 2026 Mining Software Repositories Emerson Murphy-Hill, a star researcher at Microsoft, presented his view on the role of an empirical software engineering researcher in the age of generative AI. His talk focused on three themes: the durability, differentiation, and dissemination of research. https://www.spinellis.gr/blog/20260413 Diomidis Spinellis Text Empirical software research in the age of AI https://www.spinellis.gr/blog/20260413 2026-04-13T14:06:11-00:00 en https://www.spinellis.gr/blog/20260302 We are living through a golden age of generative AI: a time when progress is both breathtaking and somehow still unable to reliably open a PDF without hallucinating the author’s middle name. The curve is real, the funding is real, and the demos are so real that they must be watched on a stage with dramatic lighting, because ordinary lighting reveals too much. The modern model does many things remarkably well—summarization, translation, code generation—and then it will confidently assert that 9 is a prime number “depending on your threat model,” which is how you know you’re witnessing history. https://www.spinellis.gr/blog/20260302 Diomidis Spinellis Text Vibe coding toward the incident horizon https://www.spinellis.gr/blog/20260302 2026-03-02T16:44:31-00:00 en https://www.spinellis.gr/blog/20251223 Several news outlets reported the discovery of a 1970s Fourth Edition Research Unix magnetic tape at the University of Utah in July 2025 and its successful restoration. This is a significant find, because up to now only the Fourth Edition’s manual was thought to have survived. Over the past few days I incorporated the tape’s source code into the Unix History Repository hosted on GitHub (see it here ) and studied the code’s composition. https://www.spinellis.gr/blog/20251223 Diomidis Spinellis Text An initial analysis of the discovered Unix V4 tape https://www.spinellis.gr/blog/20251223 2025-12-23T18:18:55-00:00 en https://www.spinellis.gr/blog/20250926 My colleagues and friends know that I prefer to communicate with them via email rather than chat messaging. There are many benefits in such a choice. You may want to consider them and adopt the same stance. https://www.spinellis.gr/blog/20250926 Diomidis Spinellis Text Why I choose email over messaging https://www.spinellis.gr/blog/20250926 2026-03-02T16:47:22-00:00 en
