How do you get iron ore in quantities that would allow to build anything worth building & maintaining?
(And what would you possibly use a resource-extremely-hungry steam engine for that needs to be fed that a wooden watermill couldn't do? You would need to build up society/economy even to justify a usecase for a watermill, otherwise you just build a monument.)

You could build an electric battery 10k years ago, but what for?

Where do you get species directly suitable for animal husbandry?

Or ppl to produce & use higiene products?

I can go on but in short there's loads of knowledge pretty much anyone can bring to 10k years ago that changes lives significantly.

I absolutely agree with that.
