I absolutely agree (I didn't say it wouldn't change things), but the first decades/generation would still be pretty basic, much of the knowledge wouldn't be applicable until you build your tools, get basics sorted, build safety nets, etc.

I'm trying to make the distinction between the ability to just 'make' as a proof of concept & actually apply that knowledge at scale that makes any difference in that accident context. Like metalwork - without (smol-)city-sized communities (labour, and accumulated resources like winter food & shelters) it doesn't make sense bcs you don't end up with enough use-cases.

(Ofc immediate location is a great factor in what knowledge is more applicable and what not - surviving in the Arctic circle would be much different to the some savannah).
