> if you ignore electronics. And materials science. And medical science. And probably several other things I'm not thinking of right now. The truth is that the electronics you mentioned are a force multiplier. It's like saying 4,000 years ago, we had everything we had in the immediate pre-renaissance. The math was the enabler that gave us the ability to exceed what we had. Electronics (and the things that go along with it, such as the software to run it) are what allow us to move vast swaths of other tech forward. We are still limited by physics, and we won't ever find ways to circumvent physics, but we'll find ways to not have to circumvent physics.
