I wouldn't say that human brain is that efficient (per volume). Compare and contrast with the brain of rats or Corvidae: https://www.youtube.com/watch?v=ZerUbHm

  It's not even a good example. Humans are about the least physically agile vertebrates on the planet. Think of a fruit fly. It can walk, fly, forage for food, mate, etc. The entire critter has a mass of .2mg and their brains have ~135k neurons. Making the horrible assumption of linear power scaling, that's one microwatt.

    but can it do math? can it paint? drink wine and muse on its own brain efficiency?

      Fruit flies can drink wine. Doing maths - well, it is a common trope that we extrapolate skills of a fraction of humans on the entire population. For an average human 1/3 + 1/2 can be problematic. Abstract counting up 5 or so - well, many birds can do that, including pigeons.

        the wine part was a joke. especially because fruit flies definitely appear to be attracted to fruit, wine, etc i believe you are underestimating how capable humans really are. all of us can learn to do math and i’m talking serious math not basic math.

          My point from above is that 'humans playing tennis' isn't a great benchmark for the efficiency of our brains.
