This is absolutely how we understand the technology now, but I think it's worth noting that computing luminaries also thought "640Kb of memory was more than enough for anyone" and that "eight mainframe computers will serve the computing needs of everyone across the planet" at one point in time, too. Quantum computers are definitely overhyped and that may be all they're good for, but it's also possible we'll figure out how to do some crazy shit with them in the future, too.
