Ummm...yeah. Just listened to it. Trust me. The guy is an idiot.

He has no idea how a quantum computer works. He doesn't even understand basic physics of flight. I know people at JPL who helped design the aircraft that can fly in the thin atmosphere of Mars. So he destroys all credibility he might have right here. And the fact that he isn't even smart enough to do basic research on this topic, which is easily understood and available, should set off big warning bells in your head.

He seems like the kind of guy who would say the moon landings were faked, or the Earth is flat. He throws just enough genuine information into his speech to make it seem like what he is saying might have a kernel of truth, but then he blows it by making some wild accusation which completely ignores the 99 other possibilities all of which are much more likely than anything he said.

No. Q is not a quantum computer. They don't work the way he implies. Yes, under some circumstances you can run Shore's algorithm to break encryption. And Graves algorithm is slightly better than classical at a completely different class of problems. But there is no general purpose algorithm for a quantum computer. They can only do very specific problems using present technology. They don't view different world lines or any of the other metaphysical garbage he suggests.
