We'll have the technology either to self-destruct, or \[to\] seed our cosmos with life. The situation is so unstable that I doubt we can dwell at this fork in the road for more than another hundred years. But if we end up going the life route instead of the death route, then in a distant future our cosmos will be teaming with life, all of which can be traced back to what we do-here and now. I don't know how we'll be thought of, but I'm sure that we won't be remembered as insignificant.” [Max Tegmark](https://sms4smile.com/quotes/author/max-tegmark/) ## About This Quote This interpretation was drafted with AI assistance.
