Formally speaking, that point has been crossed in an absolute sense
sometime around 1990, with the introduction of SMM in 386 and 486 CPUs.
Since the rise of ARM as a major computing platform (ARM always
includes some sort of a "trusted" execution environment), coupled with
IME and it's twin on AMD chips, the point has basically been crossed in
all meaningful ways.

What's to be done? Well, excepting use of ancient 386 CPUs or building
general-purpose computers with overgrown Z80's, we do have these things
called FPGA chips. Some of them are monsters that have as many logic
gates as the early SoC's from 2010's and can push those gates at or
over 1GHz. There are also more modest FPGAs, and among these you can
find quite a few models that can be used to build a FOSH computer.
Until foundry access becomes democratized, this is the way to go if you
want CONTROL over your computing.

(The relevance of all this to 9fans is that Plan 9 is sufficiently
simple that it might be the best previously-existing OS to port to
these to-be-made FOSH computers. Which reminds me, I need to look into
the Plan 9 VM.)
