For a lot of academics, the preservation of knowledge is super fascinating.
That said I don’t think there is anything exceptional about video games in the larger scheme of things. Media, like cassettes and VHS will also suffer from this issue. If you’re a Star Wars fan here’s a random example. There is apparently a stockpile of Star Wars books turned into audiobooks accessible only for the disabled and blind. This stock is stored in some Congress library. That fact always interested me.
The situation for scientific research is similar. A lot of computational work done in the 60s-80s is lost because the media was not backed up or preserved. So thousands of scientific papers are not easily reproducible. I remember looking into a famous paper about climate change models published in the 70s. They recently asked the author if he still had the codes that generated that model and he basically said “heck no”. So all that knowledge is lost. We’ll never have an exact duplication of that important work from the 70s.
Same goes for a lot of the internet in the 90s. Some of it was backed up but a surprising amount is lost. Projects like the Internet Archive are so important for humanity’s preservation of data.
So yeah, the video game situation is interesting but in the grand scheme of things in the early tech era, it’s normal. A lot has been preserved via roms.
