Your answer boils down to: "I know this technique, I don't want to learn blub technique. My job is to get stuff done, not learn new techniques." In which case, good for you; enjoy your sync code (seriously), and please stop telling the rest of us that have learnt the new blub technique that we shouldn't use it.

Nope, my answer boils down to: "I said I never had much use for one. Never said I didn't know how to use it." (c)

Honestly, your dismissal of its value sounds very much like you don't know how to use it. The whole argument can be turned around and the same said about threads, which are not "simple" as you suggest if you don't already know how to use them. You might as well say "simple async".

If you carefully read my message, I said there are cases where async is beneficial. Most of the time I don't think even threads are necessary. E.g. the most common application nowadays (arguably) is a web server. Of course those who write web server itself may use whatever technology that fits, but for us mortals who simply want to receive request, query DB and respond with data, even threads have a very limited usage. Why? Because web servers are highly parallel, you try to make your request processing parallel and you starve another request (DB is a limited resource, and most web apps don't require computational power). So a simple sync processing works just fine -- no headaches, no mental overhead and you can focus on the business logic, that's what your employer values the most. The exception is when your company name is Twitter or X, whatever (which the most of web apps are not). Other cases? Depends, but the same approach applies: we usually have a bottleneck somewhere else, so you are trying to be smart and starves that. And introducing a sophisticated approach where it's not necessary you shift the focus from the business logic (see above).

Also parallel execution is never simple, there are multiple problems no matter what technology you use, be it async or threads. Meanwhile there are different threads too, you know, green, system etc. There is Erlang for example, which existed long before async was invented. Async is just the current hype, which always starts with "we solved this specific problem, let's do it everywhere!", then ... yeah, we did, but only for this special case, but then it creates tons of problem elsewhere, but we are not going to look there, and if you are looking there we will declare you simply not able learn our new shiny thing. Been there, seen that. Even had this mentality.
