<p>A coding model that can make genuinely well-considered data structure choices won't be a LLM, it'll be something more general.</p>

<p>It's because they don't know data structures.<p>"Show me your flowcharts and conceal your tables, and I shall continue to be mystified. Show me your tables, and I won’t usually need your flowcharts; they’ll be obvious." - Fred Brooks, <i>The Mythical Man-Month</i> (1975).<p>and essentially the same sentiment, three decades later:<p>"Bad programmers worry about the code. Good programmers worry about data structures and their relationships." - Linus Torvalds, git mailing list, 2006.<p>These things have not changed even though everything else is topsy-turvy. As-of current writing, I have yet to see an LLM make good data structure choices; they go for something that is superficially plausible but profoundly ill-considered (or rather, not considered at all), and then commonly burn tokens treating this implementation detail as a design invariant and trying to deal with the consequences by writing more code, instead of iterating directly upon the ill-fitting data at the root its problems.<p>If you're wondering, "does he mean the schema of let's say a db or other persistent store, or does he mean abstract/algebraic structures", the answer is yes to both, I think coding models are today shockingly weak when it comes to design reasoning in both domains.<p>Fortunately, their suggestibility means the same models will readily accept direction on the matter (perhaps even more so than on the structure of code), so I recommend doing just that, and (bonus!) this means your CS degree is still relevant.</p>

<p>Unfortunately, “popular language/ecosystem” includes JavaScript and PHP.<p>I’d go for “universal and timeless”, which has meant C for several decades now. There is, I’d concede, a reasonable chance that Rust obtains that label in our lifetimes.</p>

<p>I have seen Fable’s reasoning talk itself into ignoring an unequivocal prompt directive not to write comments, and then be startled by the precommit hook that rejects it.  It is almost desperately predisposed to emit prose. And horribly turgid, waffling prose, to boot. Claude has been like this since Opus 4.7 though, i.e. (probably) predating the introduction of watermarking.</p>

<p>My Acorn BBC Model B booted straight into BBC BASIC as well, and I too thought it was awesome and taught myself BASIC straight away, and then 6502 assembler and latterly BCPL and so on.  I was even younger than OP.<p>But I think we were the exception, even if we didn’t realise it at the time.  In hindsight, my interest was most definitely not shared by my peers.</p>

<p>> If you take the state of the brain and then run it again, replaying the inputs, you get the exactly same behavior again.<p>This in itself is a colossal assumption and very far from axiomatic.  Roger Penrose disagrees, and his theory of mind may not be in high favor, but it is not nearly so wishy-washy and self-serving as the voodoo horseshit and circular reasoning dispensed by the LLMs-are-sentient crowd.</p>
