> you wouldn't necessarily expect ancestral "defaults" to be optimal

I like the term ancestral defaults and indeed, we've come a long way since then and our biological and environmental reality is substantially different.

There is this book series Mortal Coil by Emily Suvada which imagines a future where technology has advanced enough to allow one to tweak their genome as easily as we use apps on our phone today. It was a fascinating read.

As true as it might be, that does not mean that it is possible to work around evolution to change ourselves to fit better with the new reality.
