OK, but that doesn't explain why D-Wave has so many paying customers (Google, NASA, Lockheed Martin, Los Alamos National Labs, University of Southern California, Temporal Defense Systems, US government, CIA/In-Q-Tel).
Even if one insists on "argument from authority", paying customers means nothing.
Satisfied customers, now, that's a whole other thing.
Because I like reading arguments from authority -- especially ones based on the premise that major organizations never buy into BS.
Which I guess explains why software sold to enterprises is known for its quality and utility.
