Good point. Rust also hat the problem that it is really hard to learn and requires a lot of skill and experience to do so. Which makes the risk of Rust prematurely dying a lot more real.
On the other hand, while I am not convinced that Rust really makes code more secure (the incompetent will just make harder to find mistakes, but attackers can now use AI to help with that), that it is hard to learn may have that effect. The most serious problem we have in the software space is tons of incompetent and semi-competent "coders".
Still, "standardizing" on a supposedly "secure coding" language that hilariously does not even have a full specification is probably not a good idea.
My take is all that "move to Rust" is half-assign things and misses the point. That never goes well.
