The effect of Meltdown and Spectre in our communities

Maybe "Sysiphean" is a better word than "mad", but it's ultimately a losing game. The CPU *can* access any byte of memory, and no matter what walls you put up someone will find a way over, around, or through them eventually. (Even if you had a dedicated processor for each ring, which is a cool idea, you still have to have some kind of hyper/supervisor, which just kicks the same problem up a level.)
