That is true for lots of other things. What's the point of building the Taj Mahal? What's the point of running a marathon? What's the point of getting the world record for the longest time spent underwater? Just to show that we can.

> Elon's plan would make a lot more sense if Mars was an Earth 2.0 and we just needed to move a bunch of people there, but it's not and even if we do find something really close to Earth with JWST, it would take centuries to get there.

I agree that we probably won't be able to have a viable Mars colony in our lifetime. However, I do think that the pursuit of that goal will result in lots of useful inventions; just look at what SpaceX has accomplished already.

Making a reusable rocket is not the same thing as a sustainable settlement in a hostile environment. I mean sure ...why not other than it's a huge waste of resources.

Musk aside, I think there is huge value in knowing how to sustain human life indefinitely without the earth. In fact, I think its inevitable that humans will need to leave earth at some point in our future.

It may simply be as a result of population and overcrowding, it may be to flee war and persecution. I think there is a small chance we have already made changes to our atmosphere that make life here incompatible with humans.

Its possible that within just a few hundred years, humans need to live entirely within climate controlled environments. If I had Musk level money I would be working on this now.

it may be a hot take, but yes. A lot of humanity has indeed been ways to show off how big someone's dick is, or as a dick measuring contest.

The moonlanding was an amazing but ultimately useless landmark in the grand scheme of things. Very little of the tech used back then is useful for a practical space supply line. The ability to launch out of our atmosphere and later put sattelites into orbit was 90% of the worth of such resarch 60 years later.
