    They're cryptographers (or, at least, two of them have cryptography doctorates, and are well known in the field). Cryptographers in generally are pretty warm to the idea of imminent quantum supremacy, as it's a motivator for a lot of interesting research. By which I mean, if you surveyed academic cryptographers outside of Google, you might get a pretty comparable answer.
