world changing.

many devices we have now people take for granted and are abused. that's why a world changing device would have to be something people are unable to abuse. that's why i would want to create a machine that turned water into food but any choice you want for the fact that it cant be profited nor abused. at least not to standard use and abuse. but my idea is a world where hunger and choice food is no longer a problem. that way humans will concern less on surviving and more on evolving.
