I think someday and because the ultrarich wants to live forever and trying to do it medically, but it can't be done. Just can't. However, there is one way....; matrix.

I truly believe we will be able to take a snapshot of every single braincell activities and replicate them in a computer. Then place you in a virtual world of your choice to live however long your funds allow you to. One random day as you agree to this, when you goto sleep, you'll be moved over to the digital world and you wake there.

So the long tail of any long living cloud computing services like AWS will one day host your brain at a monthly fee. That monthly fee will entitle you to a world and a life of your choice.

I cannot see this NOT happening. We will soon discover that trying to stretch out human lives is all but impossible, because even if you could stretch another 50yrs or even 100. What aliments awaits you on a daily basis? Have you seen a tortoise at 200yrs old?

But digitally replicated, you would be free of ALL things that holds you back both societally and humanly.

Then when your funds runs out,... lights go out just like that. No pain, suffering and to make sure you can't really calculate your "final" days. Your days in a virtual world would be a repeat of one of your favorite days but you won't know that it was. The beauty of that is you get to live your fav day over and over and over...
