But if you factor in over the life time of the program, Where Node saves you a week times at the initial implementation and you paid back in extensive monitoring, it is probably safe to say Rust's TCO is much lower.
Not Sure how Rust will flare against Go. But I think there is a high probability that Rust is better in the longer run.
I guess it will be domain dependent. Go uses a highly-developed concurrent GC, which is going to make it a lot more convenient for certain specialized workloads that involve graph-like or network-like structures. (That's the actual use case for tracing GC, after all. It's not a coincidence that garbage collection was first developed in connection with LISP. And yes, you could do the same kind of thing in Rust by using an ECS pattern, but it's not really idiomatic to the language.)
