Here's hoping. It's not that there's no new ideas, it's that they don't deliver VC sized returns. The only thing that delivers the returns investors are looking for are Ponzi schemes.
There are ideas that can deliver VC-sized returns but they depend on a system state different from ours - scaled up energy system, housing market, education system, manufacturing capacity, research capacity, etc etc. Until we unscrew the current status quo, we(USA) will continue limping through these innovations without the capacity to fully utilize them.
