This meme is really only true for things like Slack where the app is just the webpage in an app, and even then it's not quite true because Electron is a lot heavier than a webpage because it has to now run the webpage and the app - which I think is terrible.

But then also, Electron enables actual apps to be developed using web standards - which I think is great.

TLDR: Use Electron to make apps, not glorified webpages.
