Thanks for your point about death.

Death forces our species wide belief set to go through the constrained channel of education and communication, the same way that our bodily attributes go through the constrained channel of our germ-line genes.

This process lossily compresses the signals, which allows for drift or attenuation when the next generation reconstructs the beliefs and associated behaviors. Transmission also applies stress that acts as a filter to weed out beliefs that are no longer adaptive.

Pfft, death isn't necessary to evolution in the sense your implying.

Transmission of ideas and wealth - even societal restructuring doesn't require all the old people to first die.

Adapt or die. We cease to adapt and so we die. We're we as a species to overcome death individually, we would still collectively be bound by the same mantra.

Not that our evolution would stop - rather I think the opposite.

Assuming cellular commission is similar to a 30 year old and as healthy/mentally capable as a 30 something; so truly overcoming those obstacles - a 300 year old version of me would be better than the me now.

Taxi drivers brain composition changed by driving around London - I'll bet an extra 200 years will do something.

As long as our populace remain "Mentally Liquid" we will be fine - something 300 years of seeing and living constant changes should all but guarantee. Can't be yelling at the kids on the lawn for 200 years right?

I think elongation human life will be necessary in the not so distant future and I expect it to happen.
