Fantastic speculations! I think your comment on boredom touches on an important one - the effects of more and more time lived on our psychology... the accumulation of traumas and scars and neuroses and boredom... I think our mind will be the weak link there.

There has to be a cost to an extended life span. You touch on another important point - a social cost - a price to be paid not only in the cost for the procedure or the drugs - but to the social fabric and the unbearable tension between the haves and have nots.

The network effect and accelerating accumulation of wealth towards the few who can afford life extension will compound - and perhaps this will become a kind of speciation event... as it is likely that a fundamental genetic change will be required for significant life extension towards immortality.

With the inborn aggressive acquisitiveness of a Bezos or Zuck or any of the Robber Barrons of old or of today... it is unlikely that there will be any motivation to share the wealth - and instead the rate of impoverishment for the majority will accelerate. Instead of bombing a people into the stone age as we once threatened overtly, we the immortal will furiously drive the masses step by miserable step into the mud and caves of our distant ancestors, and we will become the vengeful gods of old. Vengeful and mad. Insane. Furious.

Wow. That train of thought didn't end up well. Maybe I'll try again tomorrow when I wake up on a different side of the bed! ;)

Thanks for your thoughts and the invitation to mess up the rug!

Best,
