This is not justified.

"Our computers tend to have much more memory than we usually need for most tasks, but it still makes sense to treat it as a scarce resource."

Why treat it as a scare resource, same deal with screen space. I am never handicapped by a shortage of memory on this computer and I use two large screens.

Practice should match capability. If I want to keep lots of tabs open, have lots of favorites and keep lots of applications open on multiple screens why not. If it bogged down my machine I know how to deal with that. I have not rebooted in more than a week. I probably will tonight but who wants to wait for the machine to start up. I want to walk up and be live not wait for a start up. I will reboot and shut off the monitors. Then all I have to do is turn on the monitors and log in. I will need to make notes about what I was working on so I don't forget any projects. I will reboot without closing browser tabs because then it will reload them when I come back up.

Sometimes I feel like you struggle to find meaningful topics and write stuff just to publish every day.
