I predict that quantum computing is possible but you still have to take into account the addressable market which appears to be very small. Even assuming they work perfectly, quantum computers just aren't good for much.

Yes, we will never need more than 12 quantum computers or so /s

Computers today are used to solve the problems computers can solve: this is as vastly larger class of problems than envisioned by anyone 50 or 70 years ago, but there are still many computational problems that we do not solve.

These unsolved problems are often only known by domain experts with a deep understanding of why a specific domain is addressed by a given model.

Maybe we'll have quantum cards in the future like we have graphics cards now, making it available in many devices.
If somehow they can work without being super cooled.
