There was an interesting critique of Musks futurism by Tom Nicholas. It definitely gave me another perspective.

You don't want to be on that train anyway. It only goes one way. And it will likely result in a premature death.

> And it will likely result in a premature death.

Likely is putting it quite mildly - it's likely to cause a premature death in the same way that throwing yourself off the empire state building is likely to cause some injury.

This comment is like someone saying they’re eating pizza, and responding “you’re only eating a few slices”

I think you mean the benefit of technological advances from a mars trip.

A mars trip itself is only for those going. Most people don't get a part of it unlike pizza which can be divided

So, how would you define “taking humanity to Mars”? Surely you don’t have to take all the humans to Mars.

We’d all agree that Europeans (non-exclusively) colonized the Americas, but not all Europeans went and not all had the opportunity.

You compared a tangible item being divided amoung people to an achievement for humanity as a species. They are two different things.

That's my issue

The Americas were divided among people (original inhabitants, and later colonies), and many countries & people weren’t recipients. But I’d still say that humanity has reached America.
