Yup. But two of my degrees are in engineering, so I dang well better have that knowledge. Otherwise my university owes me a refund!
Of course not. You’d be burned at the stake for practicing witchcraft. Humans have had to be dragged through their evolution.

Used to make black gunpowder with charcoal sulfur and salt peter. That may be the only contribution I would make. Would have to think about it to decide if I have any other tidbits - most of us probably have some that we don’t even realize.
If we’re talking a 1000 years ago in the US you better be pretty good at working with wood and stone, skills as a hunter gather would come in handy also. Your only tools were what you could scrap from the earth.
Already been there. It smells so bad I came back.
I know where to find lots of gold.
Reversing the question:
If the world’s technology went back in time 1,000 years, due to something like EMP that fried everything more advanced than hand tools and for whatever reason kept everyone from directly reconstituting today’s technology, what knowledge and education would we need to rebuild? How ugly would things get before we restored a stable level of technology? [Obviously pretty ugly because we couldn’t feed anywhere near 7 billion people for even one year without technology, chemical fertilizers, modern irrigation, modern harvesting and transportation.]
It would be like a city slicker moving to a farm. One wouldn’t make it at all (even for a short period of time).
No way, too many unknown unknowns. I doubt if any of us would last more than a week; the obvious problem would be sanitation - we wouldn’t be able to eat the same food or drink the same water that the people of 1015 did. Montezuma’s revenge turned up to 11, and it would kill you, end of story.
I think I would plagiarize popular songs like Gangnum Style, Achy Breaky Heart, and Funky Town and I would be come filthy rich!

It would take 300 years to recreate an iPhone..
