A scam is a strong word, giving the impression that there are malicious interests in selling it without working towards making returns to the investors. But a dead horse, for sure, it now looks like.

The next big challenge will be mounting the controlling hardware, currently connected via coaxial cables, onto the chip while preventing the introduction of new sources of interference so that error correction can run. That will take a miracle.

Of course, an alternative is a million coaxial cables connected to a chip cooled close to mK temperatures.
