I've seen toasters from the ~1930s that seem to be virtually indestructible, and which will still burn your toast just as well as any toaster from the 2020s. I can't imagine current appliances lasting 90+ years.
Smart toaster ovens may change that equation a bit, both in terms of not burning your toast (due to cameras and various sensors and control systems) and also with even more rapidly accelerated obsolescence as apps and cloud services stop working.
