My Windows desktop will routinely be using over 20GB of RAM with just Firefox with a few tabs, not even a dozen, Discord, and Teams running. It's boggling to me that people can run hundreds of tabs, even though I have definitely seen it. Watching them fumble around trying to find the right tab is also hilarious. It's like a roulette game.
