Those numbers aren’t comparable.
Go and Rust don’t have similar numbers of developers. My intuition is that Go has an order of magnitude more. It’s like comparing product reviews on a shopping website - 4.7 based on 20 reviews vs 4.3 based based on 200 reviews. It’s hard to say which is better. You’d have to go deeper into each of those reviews to learn if the pros and cons apply to your use case.
Another important metric, as OP pointed out, is the age of the code base these devs are working on. Rust devs are probably working on code bases they started and Go devs are maintaining someone else’s code base.
That said, I agree with the current top comment on the thread - Rust code based may prove easier to maintain when we look back 10 years from now.
