SpinLaunch's website claims: "To date, we’ve conducted tests over 6x the speed of sound."

However, that doesn't seem possible because the centrifuge is not in a decent vacuum (as Thunderf00t points out in his second video) due to the whooshing sound of the centrifuge 'blade', and the speed can be estimated as just less than the speed of sound. If they have the ability to do hypersonic tests already, why would they not show it in their promotional video?

The fact that they intentionally blurred the data on the screens during the demo is also odd.

Regarding your final point, it's much easier to pretend to be a genius than to actually be one; Elon Musk is a master at it. Additionally, debating skill is a very misleading measure of intelligence.
