StackOverflow went along way in killing the Tech Blog, and the number of "right" but poor answers on Stack sites are at an all time high
Often the "best" answer on those sites is buried or even downvoted in favor of an answer that "just works" but may have security issues, maintainability issues, is out dated, etc.
In alot of area's I find Stack answer to be of low quality if you happen to have any indepth knowelege of that area.
They should be renamed to ShitOverflow, because that's how bad the quality is a lot of the time.
If we don't get AGI, the LLM that are starting now and don't have fresh data from people's queries won't be able to get going. The internet will quickly become stale. This will be sped up by the spam that the LLM will be used to create.
Walking through this scenario I don't see anyway for this not to end in a network effect monopoly where one or two services wins.
