Why Is Quantum Computing So Hard to Explain?

"Even if you removed all the bad incentives and the greed, quantum computing would still be hard to explain briefly and honestly without math."

The cringe-worthy hype about quantum computers has only increased over the years, as corporations and governments have invested billions, and as the technology has progressed to programmable 50-qubit devices that (on certain contrived benchmarks) really can give the world's biggest supercomputers a run for their money.

The trouble is that quantum computers will not revolutionize everything.

Yes, they might someday solve a few specific problems in minutes that (we think) would take longer than the age of the universe on classical computers. But there are many other important problems for which most experts think quantum computers will help only modestly, if at all.
