    There is a social context that makes gender-swapping not entirely symmetrical. Men and women are not treated equally by a large portion of the population. These differences in treatment have repeating patterns and tendencies that create a bias that does not average out.

    Just to be clear, both men and women suffer from these biases. Think “provide for family”, “parental leave”, “children custody”, “real men don’t cry” for men. Women get the short end of stick in terms of autonomy and respect though…


  • Without a doubt! Humans and life in general is uber efficient in terms of energy use. Most of the energy of a car is not directly spent for the work. Work is done when moving mass from a lower to a higher place and accelerating it to a higher speed. But once you have accelerated the mass to the cruise speed, it actually does not require any energy to maintain. Rather, the energy is spent by the car to heat up the air, move it around, wear the road and the tires, and make noise.

    We use cars because they are muuuch more powerful than humans, at the cost of wasing a lot of energy. Try to push a car uphill, you won’t ever succeed without pullies which makes it even slower. Doesn’t matter how efficient you are if you cannot output the minimum power required to overcome friction etc.
