Gluten kicks ass. It’s easily the best fake meat base. I remember in college cooking a meal for my roommates and them saying afterwards “wait, aren’t you vegetarian? did you cook this just for us and not eat any?” and having to explain that no, that wasn’t beef, it was wheat gluten and mushrooms and miso. They were dubious, saying, “well, to me this is just really tender beef.”
So yeah. I’m also disappointed that gluten has gotten such a bad rap. I’m waiting for this knowledge to trickle back into the convenience foods sector so I can buy this stuff and not have to make it by hand every time, and it seems like I’ll be waiting a long time.
In addition to “format shifting,” which is a well-recognized use case, and game preservation, which is a huge and under-recognized public interest in emulator development, emulators are also used for the development of homebrew software. E.g., there’s a port of Moonlight for the Switch, which lets you play Steam games streamed from a PC using your Switch, letting it serve many of the purposes of a Steam Deck. That’s huge! It would be way less practical to develop this kind of software if you could only test on real hardware. Testing on real hardware is also essential, of course, but testing on an emulator is vastly faster for rapid iteration.
