A few weeks ago I attended Pybay 2017 in San Francisco ( http://pybay.com ). I attended three interesting talks on asyncio: Performant Asynchronous Programming at Quora: https://engineering.quora.com/Asynchronous-Programming-in-Python "https://www.youtube.com/watch?v=0iqibyfxw3w" How Optimizely Scaled its REST API with Asyncio https://www.slideshare.net/optimizely/how-optimizely-scaled-its-rest-api-wit... https://www.youtube.com/watch?v=jgLA9Hp-CvY Awaits, how do they work? https://epsy.github.io/ahdtw/#/ While none of these talks used Twisted, a few of the talks briefly mentioned Twisted when talking about the history of async style programming in Python.

From what I can see, now that asyncio is in the Python standard library, more people and companies are more open trying async-style things, and are moving to the Python asyncio way of doing thing.

During the Optimizely presentation, I asked them what the biggest pain point for them was, and the they responded that lack of asyncio support in the frameworks they used (specifically Pyramid). I think over time, more frameworks will support this, and the overall situation will improve. But overall, it seems that people are buying into the Python asyncio way of doing things. -- Craig
