What's wrong with c++?
For kernel dev it would be a disaster, there's too much implicit action, and abstractions that have unknown runtime cost. The classic answer is that everyone uses 10% of its features over C, but nobody can agree on which 10%.
As someone forced to get up to date with C++ recently, at this point it's a language in full identity crisis. It wants so badly to be Rust, but it's got decades of baggage it's dragging along.
And now there is precedent for Rust components in the Linux kernel.
It do be like that... a lot of old languages want to be Rust...
