Which Projects Need React? All of Them

    So maybe your project is comfortably nested at the “simple” 
    end of the spectrum now, but what about six months down the
    road? Isn’t it better to pick a technology that leaves you
    room to grow, rather than one that pigeon-holes you into
    bad practices?

Given that there's a nonzero chance that "using React at all" will be counted amongst the "bad practices" in that future time, this seems like a bad idea. Write the code you need today and worry about six months from now in six months.

OK. How do I put React in my network daemon? It doesn't have any GUI, it only talks using network protocols. And this type of projects are quite common in my task list.

Then, how do I put React in my CLI tool? And in my library? Not to mention desktop or mobile applications, which I don't write.

The author should sometimes come out of his web cave, especially when he's using universal quantification.
