If someone did this before with PG, provide links. Practical pragmatic example where I think this project is cool: process vs thread. There were members of the PG core team that wanted to explore it, and members who said it'd tank a project. pgrust is an amazing experimentation ground for it.

I published similar project here: www.emuko.dev - emulator for RISC-V. This one turned out to be 3x as slow as QEMU for example.

re: CTOs - if the improvement is 3% nobody of course will look at it. If the improvement is 30%, it'll be too big for big players to ignore, so as a CTO you'll be tasked with trying it out. It's really a matter of whether this thing is safe and secure, losing data or has a trojan. If the authors can prove it's all valid working code etc., it'll be a viable project.
