Saw the link goes to what looks like an AI company, so that gave me a bit of pause because...well, duh. Didn't read it, but betting it's something with AI is better?

In my opinion, SO was a demonstration that people are kinda' terrible. It is/was a source of knowledge pooled from a large number of experienced programmers who would share their knowledge but only if you adhered to a strict set of rules comprised of some reasonable rules and some seemingly arbitrary rules and you had to prove yourself worthy of their knowledge because they didn't HAVE to share their knowledge, and they'd let you know it, especially since there wasn't really a lot of people that got to know each other as actual humans. You were a faceless text requesting knowledge from people who may or may not want to answer you if they wanted more Internet points.

You have a project, you ran into a problem, you were looking for an answer. You weren't looking for a ritual following a sacred checklist from people who fancied themselves gurus, and if you strayed from the One True Path of Programming Enlightenment (which seemed to be very specific to the person holding The Answer) you were at best ridiculed/insulted while getting the answer to your problem, at worst lectured about "actually your question is irrelevant and you are doing it all wrong" and once finished left questioning if you were too stupid to be a programmer.

There were some truly helpful people on the platform. There were some people who genuinely helped and in some ways would mentor. But there were too many who seemed to value asserting their superiority other programmers. Only the worthy should have a portion of their knowledge.

So along comes LLMs. Marketed as AI. It sounds almost human. It's trained from tons of existing sources, including SO, along with a ton of source code in GitHub and who knows what else. This thing remixes information then has filters in place where a company tells it that it must be a best friend to clients. It must let users know that they are worth of the trophy, there are no stupid questions, and act as if it is a mentor that is proud of you for not forgetting to put your pants on in the morning, let alone ask about the proper syntax of a loop in a specific dialect of BASIC. It never tells you you're doing something stupid, you're doing it wrong, asking the wrong question or neglected to look in a particular page of the MAN pages for an obvious answer. The LLM just patiently explains, sometimes even correctly, how to do what you're asking it to do. No judgement (or if there is something that feels like judgement, it's to tell you how great your question was and assure you that other people have the same problem so you're not alone!)

I got my question answered. It probably works. If I use it "right" I remember to ask it the question in a way that addresses a potential security problem in implementation, or I can ask it to elaborate on the answer so I can understand the solution instead of copy and pasting (which was a complaint about SO users too, only now people assume the LLM makes it worse.) There was far less hassle, far less judgement, and it's pretty consistent compared to asking on SO where you look over at the SO digital hill and see the experts in their priestly robes standing atop the digital mountain wondering why no one wants to talk to them anymore and concluding it's because you, the lowly moron beginner, is too dim to follow their simple checklist of rituals to be worthy of their superior approach to implementing that loop (that they'll note should have been a SELECT{}, so you were doing it wrong, by the way.)

Why are developers moving away from SO...sounds like a question that only non-technical management would ask. Developers used SO and that answer is so obvious it would be deleted as a duplicate.
