Can you look me in the eye and state that you understand Bitcoin and the math and the cryptography behind it?
Even if you do, there could in theory still be a way to narrow down the key space or find some other shortcut to a wallet key, even if nobody has figured it out yet.
I understand the math and crypto behind it to a degree. I don't profess expert knowledge however. But I know enough to know the GP is wrong and I'm happy to point that out. If I thought there was any value in correcting GP claim by claim I would do so. But in reality it will just end up in me wasting my time trying to educate someone who doesn't want to be educated, and if they did they could go and research the math and cryptography for themselves.
As someone once said, I can explain it to you, but I can't understand it for you.
