This is ideal in concept, but not practical today and Peter Thiel's approach is an exception. The truth is that most startup founders start off with little money. They hope they can make a successful product, exit, then do another startup. Conventional wisdom says that those entrepreneurs will continue to make better and more success products in the future. If a breakthrough is going to happen with computers, and it will need the use of supercomputer technology, then the price of supercomputers ($1000/hour) will determine who can and can't attempt to solve the world's biggest problems. Therefore, I believe it's not the responsibility of entrepreneurs that are trying to get their foot in the door. It's for the big companies (the Googles, the Exxons, the Apples, etc,) of the world today to do it. They have the capital, knowledge and means to do it. But these companies, they are too busy trying to meet quarterly estimates and competing for market share than to dedicate real competency to some endeavor which may burn their profits and most likely produce nothing.
