1 If it would take a regular supercomputer 25 septillion years to compute an answer, how do we know that the quantum computer got it right after only five minutes, and isn't pulling some openAI style make-things-up?

2 Quantum computers are, engineering wise, also RF engineering. Not every EE you talk to is one of those. In principle, I can imagine trusting an RF engineer, a physicist, a mathematician, and computer scientist to collaborate on validating such a system in a persuasive way. In practice, Google is a bit too much of a delusional criminal conspiracy. Right now, I distrust a lot of the fundamental tools for validating systems of quantum circuits. This is a new enough area that we should not just trust that previous generations of RF engineers have explored quantum circuit designs enough to have exposed most of the failure modes. Partly because it is physicists exploring the design space. "Cool promising technology Bro", but I certainly would not stake my reputation on this or that aspect being 100% correct. (See also quantum radar at microwave frequencies. The leading authorities there recently released a paper indicating that the predicted larger sidelobes are probably just an artifact of the way that they did their original theory. No criticism of them, or the rest of the people working on that, risks needed to be taken to get started working on the idea.)

3 Russian military priorities: We need hypersonic missiles to strike targets behind heavy air defenses.
Western military priorities: We need to break RSA encryption so we can spy on everyone's private business and really make them feel that Eye of Sauron in their hearts.

4 Karl - it's an asymmetric mathematical problem.  Very hard to solve, very easy to check that the answer is correct.

Well, "very easy" meaning it takes a few hours at most on a normal computer, not that you can do it in your head.

Apple pies are delicious. But never mind apple pies. What colour is a green orange?
