I believe that the quantum era is closer than what is predicted in public. Hard to tell because quantum computing is much like A.I. in that it's an arms race. Progress is naturally secretive on just how close and how fast the research is moving, and I sense from my readings that the tech is much closer to key breakthroughs than the public at large thinks. It's also a mistake to think the tech won't move fast into the mainstream because of the cost to operate a quantum computer. That barrier will evaporate very quickly.
