english: Think of all the crazy technologies  that you could have imagined maybe humans could have developed in the fullness of time: cures for aging, space colonization, self-replicating nanobots or uploading of minds into computers, all kinds of science fiction-y stuff that's nevertheless consistent  with the laws of physics.
non_english: Denk aan alle gekke technologieën  die je je zou kunnen inbeelden, die mensen misschien zullen ontwikkelen  in de loop van de tijd: behandelingen voor veroudering,  kolonisatie van de ruimte, zelfreplicerende nanobots  of geesten uploaden in computers, allerlei science-fictionachtige dingen maar toch in overeenstemming  met de wetten van de fysica.
