These vulnerabilities will probably be around as long as we have this breed of processors, at the very least.

I can't see an obvious way to hide the processors internal state at this level while also maintaining a weak enough structure to allow performance. Maybe there's ideas cooking inside the chip companies but so far I haven't seen anything public

ARMv9 hardware memory segmentation seems promising: https://www.anandtech.com/show/16584/arm-announces-armv9-arc...

Doesn't that preclude shared memory?

This processor, that constantly shifts things around, is currently unhackable: https://m.hexus.net/tech/news/cpu/147532-unhackable-morpheus...
