A lot of the world behind closed doors is ran on older "just works" tech, I remember a job listing like a year ago in Germany for Windows XP techs to help maintain their (hopefully isolated) computers for the trains. Although, given how absolutely abhorrent the German train system is, that may not be the best example. Point is, too much software today is re-inventing the wheel using Electron, is always online from a central server, has tons of gimmicks, and uses high-level languages working so far away from the bare metal it may as well have dug a whole back to the Chinese fabs. Really hope we can see a return to more efficient low-level languages and local-only software.
