I've seen Tesla's "Summon" feature scrape the shit of the car while performing the simple act of backing out of a garage, so there's no way I would let Elon Musk anywhere near my brain lol. That said, the exponential growth of various technologies will certainly bring some remarkable--what we might even term miraculous now-- things to pass in the next decade. It would not surprise me in the least if, in 10 or 20 years, one swallows a pill of nano-bots whose task it is to pass through the blood stream and clear away plaques or senescent cells or rejuvenate telemeres. In terms of medical treatment, the advances in the next several decades may be quite stunning and radically improve both length and quality of life.
