I mean, we do have a cannons and guns age.
I agree that it’s been iteration, but the pace of iterations seems to be slowing down. Since the Internet was invented there hasn’t been a game-changing technology created.
Lots of things that claim to be it - Bitcoin, metaverse, now AI - but nothing like what we saw in the 19th and 20th centuries.
And I think that’s because huge population growth and a relatively unknown world led to huge advances very quickly. Now to make similar advances you can’t be a polymath like Newton or Tesla. You need huge investments.
Case in point: Physics. A lot of the fundamental physics from the 19th and 20th centuries can be re-created with simple materials and a little expertise. People can replicate the double slit experiment with a $2 laser pointer and a piece of foil.
But to make new advances in physics you need particle accelerators and supercomputers, and many highly educated people working together.
