idk you might need to say something more about the nature and source of this obsolescence, as you envisage it.
when I hear the phrase "human obsolescence", I think of two different scenarios: one, which is a kind of dystopian sci-fi fantasy where computers can do everything humans can, only more efficiently, which I don't think is particularly likely; and another, where certain industries (esp low skilled & labour intensive) become increasingly capital intensive and push ppl into a permanently unemployed underclass, which is a kind of perennial source of anxiety under capitalism (eg the complaints of the luddites in the 19th century)
