Let's face the truth: Electron delivers a Chromium engine, Node.JS and V8, all rolled into one package to you. So of course it's a memory hog, depending on what you are going to program, like a terminal, clipboard manager or tiny frontend to FFMPEG [all existant projects]. All those programs alone need 200 MB for the runtime engine, to just do really simple stuff.
It also needed 13% of CPU time to just draw a blinking cursor (!).
It's mostly used by shitty webhipster design startups, which are just way too lazy to learn a proper programming language, and it even doesn't fit well with the UI of your operating system. And since the underlying parts of it, when a program gets delivered, aren't for sure update as frequently as Chromium alone, it's a security nightmare as well.
