You said "within the next 10,000 years". So where's your cut-off point? 1,000? 100? 10?

There are things we need to prepare for and there are advantages to starting now. Every advance we make is a foundation for something else. I think there are things we take for granted today that only exist because of some urge to explore and learn thousands of years ago.

"The best time to plant a tree was 20 years ago. The second best time is now."

To be selfish, I'm keen to see what we can find out about our world (including beyond Earth obviously) in my lifetime. Something like the comet landing is a step along a far bigger path to getting all our eggs out of a single basket situation.
