I think a lot of modern stuff has built-in redundancy, especially tech. Computers get more and more powerful but Windows gets slower and slower so you have to keep getting more powerful machines to run it. You can't update the OS on Android phones so you have to get new ones to run the latest apps. The Space Shuttle's primary flight computer had 1MB storage and a clock speed of 1.4 MHz, over a thousand times slower than my laptop I'm using now which takes about 2 minutes just to load Windows.
