This is the what I wonder about. Is this possible at the hardware level and
still support an equally simple, understandable, yet capable, software
system on top? By extension, would Plan 9 would run on such a system or if
it would require some fundamental changes to adapt to it. For example, does
C really need to be thrown out or can it be revised.

I am in this boat too, however I have a general aversion to cloud computing
and so I would need some household multi-user systems for data storage and
heavy processing tasks or some distributed equivalent.

My trouble is that I don't trust the sealed boxes anymore after Meltdown,
Spectre, Rowhammer, etc. Perhaps simple and auditable hardware might help
with this.
