2021- The proposition to seed the next stelar system with life, to check its habitability.
Specially relevant to our discussion, is George Church presentation on day 2, unfolding the theoretical potential of a 10e9 scaledown of Breakthrough Starshot.
On the ethical side of things, the proposition is made to engineer lifeforms to intentionally seed Proxima B with these, and use these as a way to get a feedback.
The first question from the audience, and response to it by Church at 01:59. are both troubling"assuming we have a very short window of opportunity to terraform another planet, maybe we don't have enough time for finetuning, and maybe we should simply disperse DNA at greater haste ?"
On day one, a similar question was proposed at 2:53
