Yeah Elon is one of the three that seems intresting to meIt is interesting to see what Jeff is throwing his money at; and what other ultra wealthy men are throwing their money at.
Bill Gates, Elon and Jeff seem to have ensured that they don't cross paths.
Bill will own all the food and water ways.
Elon will control new energy and the objects that use them (spaceships, cars)
Jeff will control consumables entire infrastructure.
I personally like Elon's approach. He isn't after the Moon. Or Mars. He is after those asteroids and possible mining of H3 on the moon. He is a smart SOB. These NASA contracts allow him to take NASA where they want - but it's his Autobahn and they are paying him to build it.
