Imagine if he was in any other generation of players, that slope probably wouldn't have leveled off so quickly

Lots of detailed answers but the main gist is that the amount of energy that goes into changing 1g of a liquid to a gas (when it's already at its boiling point) is orders of magnitude greater than the amount of energy it takes to heat 1g of that liquid to its boiling point. So making use of a phase change means you don't need to use as much refrigerant. Less space taken up, less cost of expensive refrigerant, etc.

At least in the US, we're too busy fighting amongst ourselves, both in and outside of sports venues. Then we call the victor the "world champion."

I think that's a decent theory but it might have a big problem. If non-poisonous animals start to resemble poisonous ones, then the selection pressure for looking poisonous goes away, as there's only a limited amount of food out there and predators will inevitably realize that some of the colorful prey are tasty as well.

So if the Hover Fly evolution theory is true, then you have to either go with the assumption that food scarcity just isn't enough to push animals back towards older behavior, or you can assume that this trend towards colorful poisonous animals comes and goes in cycles.

Maybe the answer is that Earth's biodiversity reached some kind of equilibrium in the past and the number of new, colorful yet non-poisonous species equals the number of new, poisonous yet colorless species. So the generalization of "colorful animals are poisonous" is always true enough.
