I don't think it's fair to blame developer stupidity. Formulating something asynchronously makes your code quite a bit harder to read, test, etc, so it's only natural that developers would avoid that - and builtins like JSON.parse further encourage that. Note that the author of that post doesn't really give solutions for the problems he mentions, he just tells you how to detect it. Meanwhile there are actually nice solutions for the problem of handling many concurrent computations with low overhead readily available (e.g. Go).
