Powdered water? Wait, they just made a paradox. What I'd want for new tech? Portals. Robots that know we're all idiots (and prove it factually, but add "We do not intend to make you inferior. You built us for a few reasons. We know you've got a lot more reasons. Here's one: To fix all the tiny little issues. Starting with the easiest, least-harmful ones. The small issues can be ignored, but the people causing them could be given a new aim, such as making a book about it. This would keep them far too busy to do whatever it is they do wrong.") and won't go Terminator/Vex/Geth=Heretics/Vex/Borg on us.
