Tech solutions in need of problems

"Find a need, then fill it", my father used to say. This is the basis of a successful business. In the case of games, however, this also applies because the need is for amusement, even though no one ever died from a lack of amusement. Wouldn't last long in WA otherwise. Your basic premise is correct though. I've seen too much hype about things (Big Data, machine learning, etc) that will reveal themselves later as just fads.
