Electron is flash for the desktop (2016)
Here's the thing. You know what the alternative to all of these Electron apps coming out is? If your answer is "A native Cocoa/WPF app", you are on another planet, the answer is, "It wouldn't exist at all".Nobody in the last 5-10 years cared about writing Desktop apps before Electron came along, there's basically zero money in it, and it's massively expensive, both in terms of actual dev time per feature (easily 10x the cost), and also in finding specialist developers who know these dated technologies. And as for Qt, Qt has existed for over two decades - if its massive "Beatles walking off the plane" moment hasn't happened by then, sorry, it's not gonna.But now? People are making all kinds of great new apps, and more often than not, they come out on all three platforms. People are excited about the Desktop again - Electron is so good it's single-handedly revitalizing the platform that 
two of the largest tech companies in the world are behind, yet couldn't do.That is a Big Deal.
