While those primitives you mention make it possible to get a correct result, they require consistent and correct use from the programmers. While some of us may do this perfectly most of the time, bugs are inevitably created. This is reality.

Fearless concurrency means guaranteeing many of those problems cannot occur. That frees up brain cycles, eases maintenance, reduces bugs, and perhaps even opens up concurrency to a wider audience or set of use cases.

Every Turing complete primitive makes it possible to get an incorrect result. Every Turing complete primitive inevitably generates bugs. That’s the reality. Singling our threads because they also obey that basic law of computer science is a little selective, don’t you think?

I understand what the thing they call “fearless concurrency” is. And I will repeat again: it’s skittish concurrency. It’s for fearful people.
