This is fine and everything, but it's bad self-promotion. If you want your bosses to give you a raise, you need them to think that you have a unique, difficult-to-acquire skillset and that it's worth going to lengths to keep you happy.
Unfortunately, modest behavior rarely results in recognition. Bombast is a very effective tool, and at some level, you always have to compete against someone.
The dilemma re-emerges as one asks himself whether it is right to sit by and allow the dangerously incompetent to ascend based on mind games.
My answer used to be "Yeah, I'll just go to a place where that doesn't happen". I no longer believe such places exist.
Having a lab and doing experimental stuff is great, but choosing to stake your company's products on it should be a much weightier consideration. In practice, we see that this weight is apparently not felt by many.
So far, I know about this: https://harc.ycr.org/project/
Hopefully, they're shooting for something like this: https://www.youtube.com/watch?v=gTAghAJcO1o
The whole vertical software stack sitting on top of the hardware of a PC is generally considered a massive towering best with layers of abstractions, and armies of programmers needed to implement and maintain each layer. To say that this does not need to be so, would be taken as theoretical, impractical nonsense without any proof. Which actually would be a valid position, because doing software is so hard that generally you can't guarantee will something work without actually doing it.
So, yes, to make that point, and to have it taken seriously, he really needed such an example.
There is also a more recent example of Arthur Whitney writing a C compiler in <250 lines of C. Remarkable how productive a programmer can be when he chooses not to overcomplicate.

Note that the laptop he is presenting on is not running Linux/Windows/OSX and that the presentation software he is using is not OoO/PowerPoint/Keynote. Instead, it is a custom productivity suite called "Frank" developed entirely by his team, running on a custom OS, all compiled using custom languages and compilers. And, the total lines of code for everything, including the OS and compilers, is under 100k LOC.
