I don't think talking about "timelines" is useful anymore without specifying what the timeline is until (in more detail than "AGI" or "transformative AI"). It's not like there's a specific time in the future when a "game over" screen shows with our score. And for the "the last time that humans can meaningfully impact the course of the future" definition, that too seems to depend on the question of how: the answer is already in the past for "prevent the proliferation of AI smart enough to understand and predict human language", but significantly in the future for "prevent end-to-end automation of the production of computing infrastructure from raw inputs".
Olli Järviniemi made something like this point:
Rather, I expect the issue is expecting to have a single discrete point in time at which some specific AI is better than every human at every useful task. Possibly there will ever be such a point in time, but I don't see any reason to expect "AI is better than all humans at developing new euv lithography techniques", "AI is better than all humans at equipment repair in the field", and "AI is better than all humans at proving mathematical theorems" to happen at similar times.
