I'm familiar with the term (as popularized by http://asyncmanifesto.org/) but perhaps 'async' is not enough of a self-sufficient term. Something can be async but also happen to be poor.
I agree and there are benefits on some sync activities too.
Being better is another thing after we understand and adopt necessary concepts/strategies like 'async'. But without those the ability to improve would be more limited.
