You're right, what I meant was that our species, homo sapiens branched off not that long ago, about 300k years. From what we were then to what we are now in an astronomical blink of an eye. And given the exponential growth of development and innovation in the last couple thousand years. And to think we still 400k years to go on earth is just mind boggling.
- _Algernon_ 4y agoVery little happened in those 300k years which is why we survived so long. There are a lot more human created existential threats now than 500years ago such as climate change and nuclear weapons. If shit goes wrong enough just once the next 400M years we have a nuclear war on our hands. Even extremely low probabilities are likely to occur over such long time ranges. Add to that that bootstrapping a new complex society like we have now is going to be a lot harder without easily accessible fossil fuels and it seems highly unlikely that we will survive in such a way that we could save life on earth from some future crisis.
