Many people talk about the negativity, and they are right, but I think the reason more than anything is the waiting. On SO a good question might get answered in minutes (if it was easy and someone was karma farming) but it could be days or weeks for general purpose stuff; compare that to a few seconds for an LLM its a no brainer.
Maybe if in some cases stuff actually got deprecated and points did actively decay it might have worked... But can't remove power from those who had it for years...
That's hardly a death sentence. More likely just the gradual adoption of higher level frameworks and languages with less ugly parts.
