they might not have eyes.

And so if you lived on the Europa surface, having eyes wouldn't be very useful.

If you lived on a very dark planet on the tightly locked night side of an exoplanet, having eyes wouldn't be particularly useful.

So it's kind of a presumption of us to think that video is a useful form of communication.

It seems like a fairly obvious thing to do for our survival, right?

There's a high risk if we are...

committed to trying to keep this human experiment going, putting all of our eggs in one basket is always going to be a risky strategy to pursue.

It's a nice basket, though.

It is a beautiful basket.

I personally have no interest in living on Mars or the Moon.

I would like to visit, but I would definitely not want to spend the rest of my life and die on Mars.

It's a...

It's a hellhole.

I think the idea that this is going to happen in the next 10, 20 years seems to me very optimistic.

Not that it's insurmountable, but the challenges are extreme to survive on a planet like Mars, which is like a dry, frozen desert.

with a high radiation environment, it's a challenge of a type we've never faced before.

So I'm sure human ingenuity can tackle it, but I'm skeptical that we'll have thousands of people living on Mars in my lifetime.

But I would...

relish that opportunity to maybe one day visit such a settlement and do scientific experiments on Mars or experience Mars, do astronomy from Mars, all sorts of cool stuff you could do.

Sometimes you see these dreams of outer Solar System exploration and you can
