Yes and the big heads in this case don't want to share that knowledge, because why? Because they are treating the kernel like their pet project that they own and control, and they don't wanna lose that control, rather looking at the bigger picture.
It's kinda obvious that rust is the way forward as google has clearly shown, so why are they gatekeeping?
There's no solution, they need not only to accept that rust is going to be part of the kernel but also that it's a good thing. Otherwise how do you cooperate efficiently.
And also if they are so big brained, should be easy to learn rust then, I mean I'm pretty small brained and I know rust.
