On the subject of 'I read somewhere...'
I read somewhere that there is no evidence that greater intelligence is a survival advantage. The jury is still out.
Given that we are right up against three of the potential survival 'filters'- global war, rampant overpopulation and environmental destruction- the verdict might just be 'nah...'
Lots of species out there, all falling at some hurdle?
Hopefully JWST will find some evidence of life and/or intelligence in the atmospheres of exoplanets- excess O2, CO2, etc.
Hopefully not U238 & friends.
