The takeaways in this article are much more why Go's memory model becomes difficult at scale. When you're dealing with memory at Discord scale garbage collection is hard, for example on the mentioned Discord microservice:
There are millions of Users in each cache. There are tens of millions of Read States in each cache. There are hundreds of thousands of cache updates per second.
This is something that is probably never going to be hit locally in the development toolchain. You can certainly prefer the Rust memory system to Go and have that be a valid reason to use Rust over Go for something like dev toolchains, but you're not going to hit scale problems like those mentioned in the article.
