Having been working with computers professionally for almost 40 years now I've seen quite a lot of things come and go. I'm not convinced that LLMs will stick around for that long although they're currently doing better than "fuzzy logic", which is what it used to be called when they could run on 68HC11s ;-)

You know what has stuck around though?

Thumping great Unix boxes running SQL databases.

Yes, there's a lot wrong with the whole concept, but everything else is in some important way worse.
