They exist. You can buy a Lenovo Kaitian-series dekstop in China with a Zhaoxin chip. They also have a bunch of laptops. You can't outside of china because that's their agreement with Via. You can still find them on Alibaba sometimes.
That's a problematic metric as well because we don't know how much area the assist circuit takes up. Modern high-density SRAM cells cannot operate as is, they need an assist circuit to compensate for variations. For example for Intel's 10nm SRAM, they claim 77% area effiency (https://fuse.wikichip.org/news/525/iedm-2017-isscc-2018-inte...). But without those values, just bits/mm2 or so is problematic.
Boom isn't nearly as relevant as what Esperanto is trying to deliver. In fact, one can say Boom is the reason why companies have been reluctant to switch to RISC-V. Experienced engineers don't want a generator or other tools such as Chisel. They want standard synthesizable code and IP cores that were optimized for leading edge processes using standard CAD tools. This is what Esperanto is promising and is far more important than Boom.
> "The robots will now only be allowed to operate within certain industrial neighborhoods, on streets with 6ft-wide sidewalks, and must be accompanied by a human chaperone at all times."
So basically defeat the entire point of having autonomous robots doing their job?
The problem with those explanations is that they are pointless. Unless you're still in college taking a C course, most people understand that macros are substitutions.
