Is this being downvoted because of the tone, or because state machines are unpopular/inappropriate in this case?

Genuine question, because this feels like a sensible solution to the problem as stated in the article.

It made no reference to the 'shared' in 'shared state'.

No mention of asynchrony, multithreading, or the race condition that TFA encountered.

The “attempt 2” was literally a state machine implementation which the author rejected because they didn’t know how to do it properly and so did it badly using a bunch of if then else logic.
