It wasn't a core issue?

It may have had to do with the lack of magnetic field keeping the atmosphere bound.

It may have been a solar flare.

Mars is a smaller body and the Earth is more robust in that sense.

So my point is we should feel that it's a blessing to be here on Earth next to a star that is...

in the middle of its life, and within a billion years would be too bright to allow for liquid water on the surface of Earth.

For now, let's enjoy the party while it's lasting.

But at the same time, let's recognize the fact that we need to leave Earth in order to survive in the long term.

So if we want to build any monuments that will be remembered by historians of the Milky Way galaxy,

Nobody would mourn humanity if we were extinguished tomorrow as a result of World War III with atomic weapons or as a result of climate change or as a result of something like AI taking over, whatever scenario you have in mind.

there is nobody out there that would say oh too bad humanity that was fun to have around you know we will just die and that would be it and there were lots of civilizations like ours that perished probably and those tragedies are not remembered the only way for us to be remembered in the long term is to leave earth on a space platform that carries humans

in a comfortable environment.

We started in the jungles of Africa, and 100,000 years later, we live in high rises, in cities.

So in the jungle, we had to fight for resources.

If we get a banana, then someone else cannot have it.

Now we can call DoorDash or whoever, get it to your front door.

And that is a huge transformation that humans were able to make.

I argue that going to space is less of a leap because it will still be technological, but instead of being in a high-rise, it would be in a spacecraft.

But you need to generate artificial gravity.

That's a huge investment.
