It's the only real solution if you need tens of thousands of concurrent tasks. Real threads use too much memory.

That is a false dichotomy.

There are other options than async/await and threads.

We have been doing asynchronous programming for many decades.

Or you use something like goroutines or Elixir processes where green threads are preemptively scheduled.
