What I find fascinating is the extreme efficiency of what is effectively an electric motor, reaching nearly 100% efficiency. At human scale we struggle with heat dissipation and friction
But at the same time the motor is extremely finicky/fragile in the source of energy (negentropy) it will accept, while natural life is extremely hardy and adaptable.
I wonder how much of machine-like "efficiency" is actually "overfitting" at the cost of robustness.
Article stopped exactly where stuff got interesting.
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.
> Which if you want an actual feel for the true scale of things
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.

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.
