Scientific progress has slowed, but engineering progress is only just beginning. For instance, the electronic transport chain of respiration/photosynthesis, is a series of quantum tunnels. Man has barely scratched the surface of quantum-level control which nature already exhibits.
The number of transistors produced in 2021 is a bit mind boggling if you do the math. These are nanotechnology produced at a rate by humans that rivals any large physics number. By my calculation, Apple alone via TSMC produces something like 1x10^18 transistors per year. Add up Intel, Samsung and the rest of TSMC's customers and the number goes far higher. We are so used to it, we don't boggle at the concept any more but we should.
