> medical doctors would be useful, as would most scientists and engineers
A small subset of them would be able to apply a small subset of their skills and knowledge. Without infrastructure and technology, very little of what scientists or engineers learn is remotely useful, and most of that is stuff they learned in high school. The medical doctor only fares little better unless they specialized something like trauma surgery.
Without electricity and advanced industry, we're nothing but particularly clever monkeys.
