Mighty is such a great example of attacking the symptom(s) of the problem ("Chrome/the web is slow") rather than the root cause (rampant page size/complexity bloat, inefficient use of RAM/CPU, etc.). What a waste of talent and money.
We should be talking about ways to either 1) make it possible to develop performant and resource-sensitive web apps, or 2) make it dramatically easier to make native/native-feeling apps in a way that doesn’t involve so much legacy cruft.
The lack of a solid reason #2 is why Electron-based apps exist and are thriving. Making native apps for each individual platform is hard and resource-intensive.
I have long been a proponent of native apps, but I will be the first to admit that it’s not that simple for small/resource-limited teams. The rise of Electron/etc. is a failing of the pro-native segment of developers. We need a better alternative.
