I can tell you guys work with languages like Go, so this isn't true for yourselves, but I usually find it is developers that only ever work with synchronous code who find async complicated. Which isn't surprising, if you don't understand something it can seem complicated. My views is almost that people should learn how to write async code by default now. Regardless of the language. Writing modern applications basically requires it, although not all the time obviously.

Hey, I'm one of the (many, many) people who made async in JavaScript happen and I find async complicated.

[markandrewj]

Hey Yoric, I do not want to underplay what it is like to work with async, but I think there has been a lot of improvements to make it easier, especially in JavaScript/ECMAScript. It is nice not to have to work directly with promises in the same way that was required previously. The language has matured a lot since I started using in Netscape Navigator (I see you formerly worked at Mozilla). I think coding can be complicated in general, although it shouldn't have to be. I think having a mental model for async from the start can be helpful, and understanding the difference between blocking and non blocking code. A lot of people learned writing synchronous code first, so I think it can be hard to develop the mental model and intuit it.

I have no problem with async in JS or Rust, but async in Python is a very different beast, and like many people in this thread I do my best to avoid the fully loaded footgun altogether. Writing maintainable Python basically requires avoiding it, so I strongly disagree with "regardless of language".

[markandrewj]

Maybe, but I wouldn't go back to Python 2 without async. It has also improved over time in Python. I have also had success using async in Python. I do understand what the article talks about however. Understanding the difference between blocking and non-blocking code is also a concept relevant to Python. In Node it's one of the concepts you are first introduced to, because Node is single threaded by default. I also understand in Go and other languages there are different options.

I will agree with what some is said a above, BEAM is pretty great. I have been using it recently through Elixir.
