We can, right now, rejuvenate individual cells on several levels. Even senescent cells can be made do divide themselves again. We can, right now, use stem cells and extra-cellular matrices to regenerate parts of our bodies. https://en.wikipedia.org/wiki/Extracellular_matrix_protein#Medical_applications https://en.wikipedia.org/wiki/Extracellular_matrix_protein#M... Now combine the two, and you see that significant partial rejuvenating procedures are not far. Depending on how fast this goes, people alive right now may very well double their life span using technology from 20 to 50 years in the future. --- You probably won't own a self driving car. Most likely, you will rent them for less than the cost of public transportation. The car you commute with will likely have one seat and a small trunk. There may not be any traffic jam any more. Parking space will move out of the cities, and shrink. Public transportation and individual transportation may blend. You can expect some changes to the way packages are delivered. And of course, cars aren't the only things that are allowed to drive themselves. Self piloting utility drones could serve a host of purposes (I can think of surveillance, monitoring, and package delivery). --- We may have recursively self-improving AI before the end of the century. Unless it destroys us all by accident (we are made of atoms the AI could use to fulfil its pre-programmed goals, if we're not really really careful), the world beyond will quickly overshoot current science fiction. (We may have other ways of creating smarter-than-current-human-intelligence, AI just looks like the more probable one) http://intelligenceexplosion.com/ http://intelligenceexplosion.com/
