Building a slow CPU means you're much closer to being able to build a fast CPU than people who can't build any CPU. Companies that want to build fast CPUs should be preferentially hiring these people.
You have no idea what you’re talking about. There’s a huge learning gap between this and a modern consumer CPU. Assembling together logic gates and understanding a simple RISC-V implementation is literally almost nothing when compared to the years you’d have to spend intensively learning just so you could get to the level of being able to design a Pentium 4 from scratch.
