So if we do come back in 1,000 years and find ourselves different, it's more likely to have been engineered differences by human bioengineers rather than by the normal processes of evolution. If we become good shepherds of that legacy, there's some hope that we will be better to ourselves, to our planet, to the... To agree among ourselves as to what would constitute better. It could be that we will select for people that have a tendency to be better stewards of the earth. I want to thank you all for coming.
