big corporations are trying to replace their entire staff with just LLMs, which cannot write code, maintain code, and update it properly without a person being involved to audit it.

As Forrest says: stupid is as stupid does.

humans need to fully investigate and verify if the LLM detected an anomaly or not

Yeah, and once detected bugs and vulnerabilities (especially those with proof of concept exploits) are really easy to verify - and people who skip that step deserve all the ridicule and disrespect they can get, because they're ridiculously disrespecting the people they're reporting supposed bugs and vulnerabilities to if they haven't at least verified they're actual and not hallucinated.

publishing a fix based on human written code alone from there. The LLM cannot be involved further at that point, as deskilling is an ever-present danger with those things.

Here I diverge from your thinking. Deskilling has been an ever-present danger since promotion to management was invented. Some managers retain their skills, others follow the Peter Principle ever upward until they're beyond their actual abilities. The need for skills remains, and I doubt computer coding knowledge will be vanishing just because it's gotten easier to do it faster and better than ever before. If anything, I'm learning from the LLMs what's possible when you have so much extra time on your hands to write unit tests, document trace matricies, keep all the design documents in-sync with the actual state of the code, etc. All the things that we have been learning how to do minimally to avoid wasting time on them, now can be done maximally, and there are benefits - particularly when working with dim-witted LLM agents as front-line coders (who work really really fast.)

CEOs have been brainwashed into believing

many things over the years. Speaking of a role better suited to an LLM....

Perhaps, if humans used them sanely, it wouldn’t be so bad.

You could as easily apply that statement to automobiles, earth movers, concrete plants...

Regarding languages: they never mattered a whole lot - by the time I was out of school I had BASIC, Assembly (several kinds), Fortran, Pascal, C, C++, LISP, probably several more - and it's all more or less the same, each with their own quirks and special supports. Mostly you just use what works in the environment you're trying to develop for. Same for libraries and APIs... More recently, I did a fairly sizeable project in Python with Claude, but much more important than anything written in Python were the user-facing requirements. When I was tired of Python taking 2-3 seconds to render a page, I consulted with Claude and we settled on Go as the next logical target. Because the requirements and their tests were fully developed / properly exercised and maintained, the re-code from Python to Go was 100% automated, all done by Claude, and it came out flawlessly - every feature identically implemented, running from the same database, only pages rendered in 0.1 seconds max instead of 2-3. Claude assures me that the Python development went 2-3x faster than original development would have gone in Go... I wonder how true that was, or if Claude is just parroting what it read somewhere; actually, at this stage I'm 95% sure it was parroting, though the models are getting better about quoting actual estimates based on LLM assisted development.

People who share textbooks, buy cheap ones…These students aren’t a profit driven entity

Actually, they are. They are a teeming horde of individual profit driven entities who might not be able to afford an education otherwise. One might even extend that analogy to Anthropic and friends, where it was more realistic for them to ask forgiveness / restitution rather than permission. Illegal, yes. But would staying legal have been the right move?

I wonder about the future of America…

No matter what happens in November, I still wonder about the future of the US, and the world.
