There are multiple differences that make Rust a better replacement for C/C++ code than Go:
* Go requires a garbage collector and its own scheduler (A Go without GC and goroutines is not Go.) * Go has its own ABI and CGO calls are slow * Rust makes guarantees about memory safety that Go doesn't do. While there are already experimental Linux kernel modules in Rust, I have only read about researchers who wrote a whole kernel in Go. But a new kernel requires an ecosystem and it is hard to see, how the industry as a whole will support this. So you would need to write Linux kernel modules in Go and it would need to have advantages over kernel modules in Rust. It is hard to see how this will come about. There is now a group of developers working to integrate Rust with the kernel. But they also have challenges like panics in the Rust core libraries and the plan to interact with the Linux kernel through a safe API. I guess it will take still a year or two before Rust code has been merged into the Linux mainline kernel. At this point, it is not obvious whether the majority of new code will be written in Rust or C for the Linux kernel 10 years from now. I don't know anything about the reasons and drivers for the Rust Foundation, but having observed the open-source landscape for the last 30 years I can say the following. Foundations usually address two main issues: funding of the core development team and addressing intellectual property rights issues. Go is very well funded by Google, so this is not a driver. Google has pooled patents with IBM and others for open source in the Open Invention Network and is able to fund litigation up to the Supreme Court of the United States. So legal issues are also no reason for a foundation. There could be a third objective for a foundation, which would be community governance of the Go development, but the proposal process works well and I cannot see, how a foundation would improve it. This doesn't say a foundation may be required in the future, but right now the usual drivers don't apply.
