<p>This can be seen as a special case of the CWA (Closed World Assumption): some systems assume that what they see is the whole world, i.e. that they have complete knowledge.<p>Your case describes a situation in RAG (Retrieval Augmented Generation), which is the special case where that happens inside a component of a bigger system, so the needed extra knowledge is actually available elsewhere in the same system.</p>

<p>What makes sense also depends on one's business model: TRI charges premium dollars for access to their systems, so there is no need to optimize for cost; trust in the answers is the currency of knowledge workers in today's complex domains.<p>At the Thomson Reuters family of companies (technically then: Refinitiv Ltd. sold to LSEG), the first foundational model (in the sense of "trained <i>entirely</i> from scratch") was trained already in 2018 (i.e., pre-ChatGPT); it would even have been earlier, but the electricity wires and fuses in the rented 5 Canada Sq, Canary Wharf office had to be replaced first at the time to deal with the current needed to serve the GPUs.</p>

<p>Because "bigger = better" does not work for highly specialized expertise, where the knowledge is <i>not</i> available on the public Web. It is naive to believe it's all open out there merely because the Web is large and we have Wikipedia.<p>If you are a highly specialized professional intellectual property paralegal, a forensic tax investigator or a post-market pharmacovigilance analyst, you will need for-profit knowledge sources, and your answers will often require synthesizing and interpreting multiple sources.</p>

<p>Donald Michie, a trained classicist specialising on old Greek, was drafted
to Bletchley Park and became a codebreaker (and Alan Turing's chess partner "because we were both not very good at it compared to the others" [personal comm.]). After WW II., he became a professor of veterenary sciences at the University of Edinburgh, and eventually he founded the department of artificial intelligence there. He is the editor of the first book series on machine learning (1950s).<p>In his lifetime, Michie published impactful papers in genetics, biology, statistics and computer science -- and classical philology.<p>A liberal arts education and a science education are not mutually exclusive,
but complementary.</p>

<p>Well done. I agree with the credits to DJ Delorie (and to Stallman, for the original GCC!).<p>The code of the O.P. is actually not so bad for a teenager; however, the variables in Spanish do not help: "[isq]" and "[der]" probably stood for "isqierda" and "derecha", so the index of the left and right subtree of an expression.<p>Speaking of Transputers, Dr. Tim King, founder of Perihelion, was another big name of the Transputer times; he sadly passed away last month (he also wrote Tripos, which turned into AmigaDOS).</p>

<p>I don't know who downvoted the parent or why, but it's a fair question IMHO.<p>The answer is there can be dramatic difference running a benchmark one time, because LLMs are not deterministic.
A <i>proper</i> methodology would ask each question 20 times and calculate the mean correctness across experiments.<p>The reason is that the temperature parameter introduces random behavior.</p>

<p>I understand you. As an AI research (actually, despite formally called professor of AI, I have historically always
called myself more specifically NLP/IR/ML researcher rather than "AI" researcher, to avoid historic baggage).<p>I am intellectually curious whether "intelligence" and "consciousness" are simply layers that can be separated from the hardware they operate on or first emerged from, but
I never had the urge or saw the point to practically replace
human beings by machines.<p>Not everything that can be done should be done.<p>When I go to a supermarket, I always avoid self check-out. Why? First, I enjoy human interaction, even if machines may be more efficient (not yet the case). Second, I don't want the people working at the checkout to lose their jobs.<p>When we purchased a GPU cluster, I felt bad when I learned that the electricity bill was going to be north of 60 000 EUR every year (that number apparently assumes no jobs are running - so 100% idle time).</p>

<p>> The parsley and condoms I don’t get<p>Note that there is a certain level of arbitrariness
involved in this association game. For instance, if a household regularly is in need of both parsley and also condoms, the fact that they are purchased together may be a result of the pure coincidence that both were empty/used up at the same time (which is also a function of the package sizes of both items). We would be much less surprised at the mined associations if we took a longitudinal,
per-household look.<p>Furthermore, a shopping basked is per-household, but not per-person: the parsley and the condom may be used by different members of the household, or be shared, or be part of a gift to someone outside.<p>The human brain also tends to make up "causal" connections between any two items, when the real reason is often much more mundane.</p>
