Elon Musk published a few hours this tweet:
"Population collapse due to low birth rates is a much bigger risk to civilization than global warming"
Robin Hanson, who is something for whom I feel a lot of intellectual respect, liked the tweet.
In my model of the world works, overpopulation is in fact a big problem. In general, the more people you have, the less resources you have to share among those people. A decreasing population would be in fact good news, although maybe not in the short term.
Can you help me understand what are Elon/Robin seeing that I am not?
A couple of extra points for the sake of clarity:
I do understand that, in the current system, having an aging population is a problem because many resources go toward people that reach an old age
AI might or might not end the world. Let's assume in this scenario that it does not and we have many more decades ahead
