LLMs enable some new things but they ultimate do not solve the underlying problem when a human lacks knowledge. I write a lot of software on my own, but I have little to no real experience in the inner workings of the linux kernel. I could invest more time, but time is a finite resource, so I invest it into various other things that seem more important to me right now.
LLMs simplified some things that used to be hard or impossible before, though. That is indeed true. They also amplified AI slop spam, which is annoying. Some humans use AI to reply to other humans; this always upsets me, because it means the other human is not only very lazy, but also does not understand why AI slop spamming other humans is like a vile personal attack. You here state (if one does that) that you are not interested in listening or communicating with that other person.
