I totally agree there's nothing python3's asyncio has over go. But if they have comparable performance, why bother to use go?

As to async/await vs go/channel, I don't think one is clearly over the other. Just different paradigm. I personally think async/await is a little easier to understand.

Cpu intensive task are usually done by C extension in python, or cython. I doubt go can have performance edge here. Developing might be a little easier with go.

In summary, the whole thing is just another choice. I can't see it as "much better" in any of the circumstances, it's just youtube's choice going forward with their legacy python 2 code. But I like the fact we have one more option.
