I was going to come back here and say "what about transatlantic flight, which has gotten slower?" --- but your point is more relevant, more immediate, more impactful.

I do believe the LLMs we're using today are the best they're going to be - for the reasons you've highlighted.

Some superior tech might displace them, but LLMs as they are seem much more likely to get worse.

I'm encouraging people to make any important queries right now and save the results. For example "which books should i read on X" - right now you get good answers, in the future it'll be enshittified.
