But this is what FB/Meta are known for. They managed to scale PHP for years. They did fork it into Hack. They do have their own extensions. But they've put a ton of time and engineering effort into it. They didn't do it because they thought PHP was a great language. It was because they already had a massive infrastructure and tons of engineers that were already productive. Doing the math they realized it'd be cheaper to keep using PHP.
The same is true here. They spent so much money getting Instagram to scale. They created Cinder to try and fold their hacks/tweaks back into Python. Spinning up some Rust/Java/Nim/Zig/Pony/Whatever stack sounds like it'd be fun... but spinning up a stack with which you're already VERY familiar, sounds like a money-maker.
I'm totally agreeing btw, I realize this came off like it might be a counterpoint.
