@seersalomon Hey :)) Thank you so much for sharing your thoughts, some great questions your dropping!!
And yes if we will all continue to stay alive an even bigger population challenge than we see today will arise. Perhaps not to begin with as it probably will be a certain part of the world that gets this opportunity.. but I believe I've heard thats why Elon Musk wants to go to Mars, so that we can both save the human race and figure out new places so to grow our population.. !
But yes, I love your questions I have never thought about "how will our human brain cope with 300 years of memories..!!! Thanks for reflecting with me. I have another post on ageing coming up in not too long :D Have a good day!
