There has to be a better system than windows and tabs for doing work on a computer. I don't know what it is, but there has to be something. I always end up with fifteen windows with 30 tabs each over two or three virtual desktops, and then can't find anything. Maybe the bad idea wasn't AI; maybe the bad idea was multi-tasking operating systems. Wouldn't life be better if all of our computers were single-user and single-threaded? No more losing windows and tabs! No more background notifications interrupting us every seven seconds! Just sit down, start a task, finish the task, then do something else. The human brain can only effectively do one task at a time. So we should force our computers to work the same way.
