Imagine 100 years ago on a forum on stage coaches, and automobiles keep getting posted. Yes Rust is the cool new thing, but I don’t see it as a fad. In fact, I see Rust turning into a best practice for our industry unless something like it but easier takes its place
I see managed languages adopting linear and affine types for certain types of high performance workflows.
Already visible in Swift, Haskell, Chapel, ParaSail, D.
Likewise I see Microsoft and Google, will keep their lifetimes efforts going until it offers a good enough experience, even if not perfect, in spite of their ramping up use of Rust.
A good example of this is the Azure Sphere, which inspite of the security marketing story the team tells everywhere with the 7 levels and such, it uses a C based SDK.
