It’s possible there’s a regional or generational gap there. If you’re pushing 110 you probably haven’t worked in 40 years. You could even argue that the ones literally working themselves to death are the very ones paying for the older generation’s happy carefree lifestyle.
I tend to use floating or fullscreen for general browsing but often you have to type something while frequently referring back to something else - for example when programming I will be looking at the documentation. Or maybe debugging something on the command line while looking at your code to see what’s going on. In those circumstances tilling is perfect.
