Yeah, I'm reminded of container escapes, VM escapes etc. There have been plenty in the past; VirtualBox E1000 (I think?) comes to mind from a few years ago. If we are to believe this model can find 0days, I'm on board with the idea it could do so in sandbox.

That's not to say I believe it outright, but people are being oddly dismissive and acting as if it's impossible to break out of a sandbox. Which we've seen time and time again that it absolutely can be.
