Fundable ideas – Which ideas are worth pursuing and which are just a gimmick

consumer side of AR/VR I can see that but maybe I'm wrong but being able to design in 3d whether its buildings, parts or possibly software could be game changing.

Also, a screen on any wall or desktop seems pretty useful.

AR/VR as a teaching platform transformative.

IOT again consumer side sure. but how do you enable "farm-tech" and/or automation without IOT?
