I don’t remember the specific prediction this guy Ray Kurzweil made about life extension.
This guy made many predictions back in the 80s. An example, “by 2009, most novels will be read on an electronic tablet” or something to that effect. Obviously the predictions get harder the farther into the future you go. I remember reading that he believes there will be a significant leap in life extension by 2040-2045. I can’t remember if he used the word “nano bots”
I’ve read other articles from magazines and books that talk about scientists developing nanobots whose job is to repair the damaged telomeres on our DNA (the thing that causes aging). I certainly don’t want to live an extremely long life, but 200 years? Hell yeah, I’ll do that if I’m happy with life.
