Did you hear? Mankind is now 300000 years old

If this is true, then what do we need to re-think culturally? Here are some suggestions from Marginal Reolution:

Great filter perhaps more likely to be behind us, if it took us 295,000 years to start having anything like civilization?

We’re slower learners

Civilization is precarious and the great filter from apes to higher intelligence is worse than we thought.

Initially & erroneously, I read ‘president’ instead of ‘present’.

Great question. Certainly the concept of civilization is an incredibly late concept, and not necessary for human flourishing.

Based on a single data point, the advanced from anatomical modernity to civilization is 50% harder than previously thought.

The moral arc of history is…even longer and bends even more gradually

That current rates of productivity growth are somehow abnormal

That there’s a bigger delta between our current environment and the one we evolved in.

We don’t have _nearly_ the cultural bandwidth to transmit all the wonderful wisdom developed over _300k years_. Much has been lost.

Our first revision might be that we have good certainty on the age of mankind. Perhaps it’s 500,000 years? What other fossils might we find?

interbreeding with Neanderthals was even freakier than we thought?

That rather than being rare – ‘the end of the world’ is a horrifyingly repetitive phenomenon for human civs.

Lower probability that other intelligent species lived long enough to develop interstellar travel or communication

There are a few more suggestions collected from Twitter at the source link provided above.  I agree with the above though – there’s no way we know now half of the things we thought we knew if 300k years of information had to be propagated via word of mouth. Granted that info may not have changed all that much from generation to generation, but why would old beliefs be maintained if there was limited capacity to hold even current information in one’s mind at the time?
