I disagree. The best thing we, as individuals, can do for future society is to guide and nurture our kids. If you don't have that responsibility (you don't have kids), by all means go all out. If you do have kids, take care of them first. I actually feel very bad for Elon's kids. Money and accomplishment isn't everything. Hopefully, they at least have a good mom. BTW, you can still accomplish other great things while doing this, but you certainly can't work 23 hour days.
