We could be a lot less humans on earth, it would be amazing for the environment, and I think we'd be as happy.
The only downside I see is economic (in the sense that everything is built with the expectation of growth). But it is to me an economic problem, and not a reproduction problem.
Because when people are happy they fuck on impetuous and fucking on impetuous generates children (modulo vasectomy and morning after pill)
It’s not about the outcome , it’s about the happiness on the way there, whatever outcome it might be.
Also when people are happy they wind up perishing by fucking around in the real world due to excessive confidence doing dangerous activities such as drinking and driving, jetski accidents, drug overdoses etc
You have to substitute these people somehow
