while I was listening to all of you and to our wonderful scientists 00:57:28 I thought of something that the distinguished physicist Freeman Dyson wrote shortly before he died he said he believed that 00:57:40 the speed of cultural Evolution the speed of cultural evolution is now faster than the speed of biological evolution so 00:57:53 what does that mean to me it's something very simple it means that we now hold our destiny in our hands and that's what you're all talking about

Our double task is now to preserve and foster both biological evolution as Nature designed it and cultural evolution as we invented it, trying to achieve the benefits of both, and exercising a wise restraint to limit the damage when they come into conflict. With biological evolution, we should continue playing the risky game that nature taught us to play. With cultural evolution, we should use our unique gifts of language and art and science to understand each other, and finally achieve a human society that is manageable if not always peaceful, with wildlife that is endlessly creative if not always permanent.

In the near future, we will be in possession of genetic engineering technology which allows us to move genes precisely and massively from one species to another. Careless or commercially driven use of this technology could make the concept of species meaningless, mixing up populations and mating systems so that much of the individuality of species would be lost. Cultural evolution gave us the power to do this. To preserve our wildlife as nature evolved it, the machinery of biological evolution must be protected from the homogenizing effects of cultural evolution.

evolution works on a much longer time scale right than than 00:35:09 any given life and so we need to we rely pretty heavily on helpful social norms right these cultural norms that actually teach us the right way to engage with each other and that can transcend any 00:35:22 one generation um and you know we worked really hard um in the west you know not just i mean this has happened everywhere but it you know we're where we're from um to acquire norms from from that we would 00:35:35 have called you know liberal democracy right that tolerance and respect and and these things and individual rights and you know it you see those things start to erode now and you start to see some of that base 00:35:48 nature taking back over the tribalism and the seeing the other as the enemy um the outgrouping of people and it we know from history it doesn't end well there right like the erosion of these norms 00:36:02 not only will continue to exacerbate collective illusions they i i think they're the biggest threat to free society that we face in a very long time yeah yeah you made a very convincing case for that
