https://www.youtube.com/watch?v=GvgTivwzcuoHe presents an interesting take. I didn't watch it all, but two early points.
He notes that the DAO *is* dead which is, of course, a pretty epic f-up.
He notes that there are only so many people who could have done this, 500 approx, meaning the hacker is not an outsider. I find this bit more worrying than anything else.
I'm an Ether holder btw so for me it is important this attacker is revealed pretty soon.
The idea that only 500 people could have done this seems somewhat absurd. The number would be substantially higher.
