Maybe a battery weight limitation?

I’m no aviation engineer, but as far as I understand it that’s exactly it. The more weight, the more thrust you need, which means your fuel (or in this case, stored energy) needs to be very efficient in thrust per kg.

It seems pretty clear that queer people would be persecuted a hell of a lot more under Trump than Biden.

Sort of? Vanguardism is inherently totalitarian, for example. The core idea is that the vanguard know better than the poor proles what’s good for them (Maoism is basically vanguardism). Stalinism is quite obviously and clearly totalitarian, putting rapid “strong” decision-making for the goal of rapid economic development above everything.

There are more democratic and equal forms of socialism, like Democratic socialism, syndicalism, mutualism (if you accept anarchists as part of the umbrella) and so on.

My core point is that socialism can be totalitarian or not depending on the actual ideology inside the big varied umbrella term.

For the families who can afford it, daycare is the replacement.

“It takes a village to raise a child” is an old expression for a reason. Historically (EDIT: And today in most of the world), parents wouldn’t take care of their kids 24/7. They would have parents, siblings, neighbours and friends to help share the load.

The idea that parents and parents alone do 100% of everything to raise a child is a very modern western thing.

I don’t know the details of this app, but if it’s specifically US streets and notes on households there, then GDPR does not apply, as they’re not mapping EU households. GDPR is only invoked if the personal information of Europeans is at risk.

I read a pretty compelling hypothesis that in ancient times the makeup of your military determines the culture, because they have the training and weapons to coup if they want something.

Female majority militaries died out because women of military age are simply less disposable than men of military age. You can’t effectively repopulate with an 80% male population, for example.

This means natural selection applied to tribes means you’re going to be left with almost exclusively male dominated militaries, which will very likely at some point decide they want more power.

In terms of the “man strong” thing, the average male is stronger than the average female, but is not really a huge factor when you’re selecting for the strongest across a large enough population.
