Vibe-wise, it seems like progress is slowing down and recent models aren't substantially better than their predecessors. But it would be interesting to take a well-trusted benchmark and plot max_performance_until_date(foreach month). (Too bad aider changed recently and there aren't many older models; https://aider.chat/docs/leaderboards/by-release-date.html has not been updated in a while with newer stuff, and the new benchmark doesn't have the classic models such as 3.5, 3.5 turbo, 4, claude 3 opus)
I think that we can't expect continuous progress either, though. Often in computer science it's more discrete, and unexpected. Computer chess was basically stagnant until one team, even the evolution of species often behaves in a punctuated way rather than as a sum of many small adaptations. I'm much more interested (worried) of what the world will be like in 30 years, rather than in the next 5.
Its hard to say. Historically new discoveries in AI often generated great excitement and high expectations, followed by some progress, then stalling, disillusionment and AI winter. Maybe this time it will be different. Either way what was achieved so far is already a huge deal.
