I don't know after 50 years as it is a long time from now but for the moment those keys are the strongest and most believable evidence that can shed light on who Satoshi Nakamoto really is.I think we should leave him,Hal "Rest in Peace" as he was the biggest pioneer in Bitcoin and a brilliant programmer mind.
I wouldn't bet on it. People like Wright would pay a ton of money for access to those privkeys. Imagine a bad actor gets their hand onto this address and offers access to it to Wright and other Faketoshis for a few million bucks. It's no "strong" evidence of anything. Satoshi remains a piece of history and at the same time a mystery. Whoever claims to be Satoshi today has other kind of interests that are non-Bitcoin development related. If Satoshi was to create something
better than Bitcoin or point out flaws, I'd imagine he'd do it the same way he initiated BTC..
