They need to generate revenue to continue to raise money to continue to invest in compute. Even if they have the Midas Touch it needs to be continously improved because there are three other competing Midas Touch companies working on new and improved Midas Touch's that will make their's obsolete and worthless if they stay still even for a second.
But most of their funding comes from speculative investment, not selling their services. Also, wouldn't selling their own products/services generate revenue?
Making a profitable product is so much more than just building it. I've probably made 100+ side projects in my life and only a handful has ever generated any revenue.
