Demanded is a weird term here. No one demands "ls", not the banks/insurance companies back then, not the Twitter users today. It's a tool, not an application. You dont buy your computer (or cloud VM) to run "ls". Back in the days consumers were not in the software picture so much. Maybe some pre-PCs were catering for home users, maybe some BBS to dial into, but that was it. This has changed. And this is why we have Twitter. > programs that need to be rewritten in new tech stacks every 3 or so years. Where do you get this from? I dont see such trend at all. Okay, some library needs to be replaced, and we share more code nowadays (the stacks are deeper, but what would you expect? more cycles to burn and more ecosystems). But no-one factors in the cost of constant rewriting to stay up to date with the hippest stacks.
