I consider all of those as nice-to-haves. We have over 7B people in the world and got to this point without the technologies you mentioned.

We already have the technologies today to allow people to live way longer than would otherwise be possible, to find and use any natural resources the planet has, and to dominate any other organism that could threaten our lives. I’m content with that.

I think it is a big mistake to be content with how crazy primitive we are today.

We can't even operate on a brain tumor that's inside your head - we lack the precision to get in there without damaging the rest of your brain.

When we want to operate at microscopic levels we continually fail.

The mysteries of how and why we age, how many diseases work, remain unknown.

There is so very much left to learn. There may come a day I might feel it's time to be content, but every second that passes I'm a little closer to death.

We should continue to strive for more. May there come a day that we can live for very long periods of time and each individual can have as much as 100 people have today.
