This might sound contradictory, but I agree with you. 300 MB is nothing!

Problem is, when the music player takes 500 (let's be honest those 300 were probably just a cold-start and before actually doing anything with it), the collaboration chat app takes another <let me check...> 650 MB (Slack right now for me), the profile loader I need for work is <checking again...> another 400. The text editor is 510 MB (VSCode, and still that is a well engineered and optimized Electron marble). The Pomodoro timer, 300 MB.

And on top of that I'm supposed to do my actual work! All that junk is stealing memory that should be available to Visual Studio and compiling my huge code base.

Hopefully we don't end up with Electron calculators, calendars, email clients, file browsers, and image editors, because those things also tend to be open long term in my desktop (which right now I can do without any second thought about being able to, because they are all properly done as decently optimized GUIs)
