Your complaint is basically saying "Hey, I don't need this professional workstation just to run Notepad, what is going on in the world?!" while professional workstations are not for running just Notepad, they are for doing a lot more things than that.

Here you are complaining that a "hello world" uses a lot of memory. Yes, that's true, but the use case for Electron is not to display just "hello world", it's to build full, accessible applications in languages who are usually native on the web.
