There’s a catch here, something I read someone mention on Hacker News and I agree. Python is easy when you don’t care about performance; the moment you need to worry about it, all the easiness gets thrown away.

I remember some old papers talking about Android’s runtime (which is garbage collected) x iOS (reference counted) in which Android was more efficient with high memory, but less efficient with lower available memory.

That’s correct. I wonder if YouTube still uses Python to this day.

Not saying there isn’t a difference in language performance, but for most world problems the architecture and algorithms matter more than the language for performance. Unless you’re in a very constrained environment such as lower end smartphones or embedded systems.
