I read back in those June articles that they were expecting to achieve quantum supremacy during 2019, but it still sort-of caught me by surprise. I wish they hadn't pulled down the paper from the NASA site, though. I'd like to know more about the problem that they were working on. Neven's Law says that quantum computing grows at a doubly-exponential rate, far faster than Moore's Law. If that holds, the gains will be astonishing in the relatively near future.

On a housekeeping note, one of the things I didn't really think about when I started this series is that over time I'm starting to build a nice little knowledge base here on the blockchain. I sort of like the way that's working out. One of these days, I'm going to have to write a script to create an index with links into all these posts based on topic.
