I think, the implication was that it attracts a disproportionate number of inexperienced yet very vocal and immature crowds. It creates and unfriendly and unpleasant community.
Also the marketing innovation or advantage it proclaims -- "callbacks as a concurrency mechanism" are thought by some to betray a understanding of how concurrency can be handled in a sane way. So anything said or promoted afterwards is discarded just based on that assumption.
As an example it is like someone saying "oh we have this new awesome paradigm invented and it is a sorting algorithms and it compares every element to each other and swaps places". And everyone will say yeah cool that bubble sort or something like that. It is not very interesting. But you know with additional marketing and a vocal community one can grow and promote that idea despite the apparent flaws at its base.
Now node has very good qualities. It makes it very easy to get started, lots of packages. A lot of example. So those are probably things to look at and copy. And if you see that presentation (or watch the video) that is what the author drives towards. Simplicity. Easy to learn. And so on.
Have to agree with the presenter. Simplicity and easy to learn are the killer features of node. Arguably, that is most important feature of any technology that one wants to work with.
As for callbacks for concurrency, I think once the language has support for coroutines (es7 generators), I think things will look more elegant.
