Same 80s experience. The idea that someone would argue or even think that software should still behave as it did back then is mind-blowing. None of the resource constraints of that era are even remotely relevant today, but we are still dysfunctional meat. There is no good reason for a word processor to not automatically save work by default - and unless someone is working with a lot of large images, even persistence of the full undo stack is not a tall order.
