Your right, I think its more along the lines of no big companies/induviduals are willing to devote all thier time/money into something with very few benifits of having. But saying that, true AI could revolutionise how we live, having robots peforming tasks that are usually dangerous/boring for a human. But then it goes down the line of what if they rebelled, what if this AI we create and utillise turns on us?
