I have no idea how people use so much RAM. I use a 16 GB machine for work and it runs perfectly. For the majority of the time I'm well below 8GB. And I do use Electron apps.
Of course, I'm aware of the possible uses demanding more than 16 GB but I can't believe this would be the case for a majority of the people.
Yeah, but those shouldn't really influence memory usage too much unless actively used, right? I'm pretty sure browsers unload unused tabs from memory.
I myself sometimes use quite a lot of tabs, although I have to admit it's definitely not close to 80 tabs open at all times.
