Carbon's own docs say:
> Existing modern languages already provide an excellent developer experience: Go, Swift, Kotlin, Rust, and many more. Developers that can use one of these existing languages should.
So the reason for Carbon to exist is gone. C++ code can be migrated straight to Rust without Carbon's stopgap.
I think that's overstating it. Carbon promises a reliable transition; getting an LLM to rewrite in Rust depends on the LLM being smart enough to never make a mistake that it can't catch with (existing or its own freshly created) tests.
LLMs are very good now, but they are still stochastic (when temp > 0), and Google has a lot of code -- i.e., many rolls of the die.
