Now, if your Rust code was a distributed system that handles spiky loads from ~330m users, and processes petabytes of data, then I'd consider your comparison relevant to Twitter.
But I'm going to assume it's not relevant.
P.S., I've written Java services that never went down, because they had a well defined domain and all potential errors were handled. But, I'm not about to compare that to all of frigging Twitter.
The infra usually matters way more than the code. RAM or a disk will typically fail before the Linux kernel, and it's written in the boogeyman language.
