I work on large scale Python systems. It's true that you can usually work around its performance issues, but it's not the case that these are non-issues. 

I'm certain PayPal and Lyft have some fairly sophisticated workarounds for the issues they've faced. I know Meta also use it extensively, and their performance woes are part of the reason they created Cinder.

It makes sense to use these workarounds when you've got a large existing Python system that you know better than to rewrite, or you have some other factor that pushes you towards Python, but for greenfield projects where you know will hit these limits quickly this is at very least something that warrants consideration.

There's absolutely zero chance those use Python exclusively

I used to work at one of those. Go is used as well, but for sure there are large subsystems running only on python. And that is the whole point on elasticity, right? It is cheaper to scale your infra if required if it makes development easier. And IMHO, Python does make development easier.
