With the current trends of the ICO's imagine a token sale where the funds would be used to develop a robot which could replace actual real life low wage jobs. With a budget of like $30 mio. it would be easy to hire 80 engineers at about $100k each (including costs for health care and benefits) which would be $10 mio. per year including $2 mio. for material and equipment. This would give the project 3 full years to come up with a prototype.
Companies like Walmart could lease the robots on a monthly basis using the tokens. This would create a strong demand and the price of the token would rise since companies want to buy it. What do you think, would this be possible?
Without idea nothing will work out. No matter whether to make 500 engineers sit in a room and provide them $100M, if you don't got working idea nothing can make the development take place.
And as far as your concern matters, I don't feel there is a need of any such ICO because similar thing already happening on the name of AI and companies like FB invested over billion in AI.
