What is there to be excited about? Having your battery drain every-time your browser runs some JS app? Wasting CPU and memory that I paid for? Lost productivity waiting hundreds of milliseconds (sometime seconds) for any UI response? I dread using any technology coming out of a SV startup, and its rather sad. I want to be excited, but can't get myself to be. As an aside, with all due respect to these startups, calling them successful is premature. They only appear successful because they're burning through someone else's money. These technologies you diss have been reliable and stable for over a decade. As an embedded developer, my code has to be running 24/7 for months without rebooting, without running out of memory, without crashing. But forget embedded, and imagine a web service. Can you truly honestly say that an app written in electron will give me that reliability? Or should we just accept that if you want to write apps using "modern" tech, you'll just have to deal with it? I personally can't imagine any web framework ever maturing and being stable enough to where you can invest money in it knowing that it will be around 10 years from now. Having your underlying technology platform in a constant flux makes your entire product stack brittle. That is a Big Deal.
