My personal dream are those little dog-robots becoming affordable and really smart. When every (middle class and up) family will be able to grow vegetables in their gardens at 0 effort and something that is a perfect security camera and like a Roomba that also cleans windows etc etc
Second thing for me is a revolution in battery tech. Imagine a laptop that lasts a month or an apple watch as thin as cardboard paper.
What is future tech that you are excited for?
