When python started incorporating asyncio my initial reaction was fairly negative. I was behaving like a grumpy graybeard programmer ("kids these days should learn how to use concurrency instead of working on a new runtime altogether!" [0]).
But after using it for a production project I have to say I'm deeply satisfied and surprised by the maturity, quality of APIs and performance in general.
I was proven wrong and I'm happy about that :)

For me it is quite bad, but just we are now used to it. In the same way that when you ask Windows users about all the bugs and problems they have with their system, they often say that they don't have any. And ten seconds later, will click "ok" on a random crash popup they didn't even read the content of.
