Re: ...And Then There's The Problem Of Old Application Software....
Well, it annoys me when we treat those who don't have technical knowledge like they're unthinking morons at the whim of software writers. They have the option to learn how their equipment works, the same way that we did, and they don't get to avoid responsibility for doing that with anything else. For example, if one of them was recording analog video onto cassettes, they might want to know which format they were using, what players supported it, which televisions supported the video format their camera was writing to the tape, etc. That information was right there in the instructions, and the file format choices are right there in the save box. It does not take expert knowledge to try to use those things.
The major benefit of computers is that, even if they chose a format they now regret, they have a pretty good chance of being able to recover it, even decades later.
I have some schoolwork, on paper, stored somewhere at my parents' house. Well, actually I don't, because they threw it away. It probably wasn't in great condition when they did that. If I complained that I had lost my precious writing, the answer would not be to ask for paper that never degrades or that my parents run a great museum of my work, but to tell me that, if I want that paper to last, then I have to take care of it, store it safely, maybe make copies so it doesn't come down to the existence of one sheet, and don't leave the only copy in the care of people who don't find it worth anything. Had I cared about the paper, I would have done those things. Computer files are not different. Some effort is needed to keep it, and people do not always care enough to go to that effort.
