I think the intention was that if you're gently coerced into working with a single thread, like with node, then you're also coerced into writing your code in a way that's independent from other threads. In theory, it's easier reasoning about doing parallel work when you start from this point - I've certainly noticed this effect before.

I don't think any reasonable developer would dismiss concurrency/parallelism as easy problems.
