alt Hacker News> The most impressive think that stuck with me is that humans are incredibly efficient, from an energy perspective, in anything we do, compared to machines.
Humans are efficient, but not across the board. Trivial counterexample: walking is incredibly energy inefficient vs a bicycle or other wheeled conveyances whose primary dissipater is rolling resistance.

That's a strange comparison. Wheels are incredibly limited in the type of surfaces they can be used on.

Now compare human on bicycle to human driving a car for energy efficiency.
We're still pretty efficient while not having wheel shaped limbs. Running like humans works pretty well. So well even that we can chase a lot of animals longer than they can outrun us.
There might be more efficient ways to move but we are pretty well equipped by evolution.
