The good news is that I think no one human is at risk of such an attack. The way I’d frame it: if you assume the NSA can break AES-256 in reasonable timeframes, or the CIA runs every single Tor node, that knowledge gets compartmentalized to such a degree that next to nobody knows, and attacks would only be used at the highest levels against the most significant state level threats. Hell, I wager they wouldn’t even risk parallel construction for fear that it’d tip their hand.
