Thinker

Congratulations, you’ve illustrated the difference between syntax and semantics. But any competent compiler also handles semantics (just in a separate phase of compilation), because that’s necessary for any useful conversion to machine code, not to mention optimizations.

repairable and upgradable*

I know it’s an absolutely banal nitpick, but I think it’s unfortunately a revelation in the current laptop market that ~90% of a laptop stays good for a really really long time, and the other 10% can be upgraded piecemeal as the need arises. Obviously this was never news to the Desktop world, but laptop manufacturers got away with claiming this was impossible for laptops in the name of efficiency and portability.

I broadly agree.

However, “Existing maintainers have every right to push back where they see fit” is tenuous when the Linux project as a whole has already (exhaustively) discussed and debated this exact question alongside all the other questions about adding Rust, and the explicit declared direction is that Rust should become an increasingly large part of the Linux kernel.
