Man, a million years from now
Although I expect to live to see 150, looking a million years ahead is a bit of a stretch even for me. Nevertheless, in the late 1800s it seems to have been quite the sport to do exactly that. (Well, maybe not.)
HG Wells predicted that after a million years, man will have evolved to a creature that is all brain, and little else, swimming in liquid food to sustain himself.
A writer for The St. Louis Republic on the other hand predicted that man will shrink considerably, and dumb down to match. This process, apparently, will start around the year 3000!

(Hm, I suddenly realize that my colouring is quite caucasiocentric. Here’s how I determined the colour: I looked at my hand. Here’s how I determined the colour of the liquid food: I Google Imaged for pepsine. Not that pepsine is blue, but I found enough evidence to make sure my swimming-pool blue wasn’t entirely impossible.)
