The speaker considers the precise boundary between physics and engineering unimportant, even if it can be sharply defined.

“which is effective in the transition from physics over to engineering and where the distinction lies doesn't.”

“It ultimately doesn't matter, even if you can actually make a hard cut. And I think the the important thing is that we need to have something which makes actual predictions, and for that the loop between the the theory people which do like the the really nice things like mean field uh neural tangen kernels um”
