This whole "protons entering bacterium and being pumped out" is exactly the ancestor of the mitochondria, that's what it does, except now the "outside" is the inside of the parent cell.
I wonder how much of machine-like "efficiency" is actually "overfitting" at the cost of robustness.
Electric motors are sort of like hermit crab shells - Hard and long-lasting, but they only exist because they piggyback off of a living species.
there's a good richard feynam video about how things feel when they're that small https://www.youtube.com/watch?v=4eRCygdW--c
Which if you want an actual feel for the true scale of things, must be multiplied by (order of magnitude) the number of bacteriums on the planet.
The caveat is that more zeros do nothing for our comprehension of the scale. That's the problem because most people can't comprehend how evolution is even possible. We just don't have a mental model for a trillion, it's all the same to us after a certain threshold.
