The older a system gets, the less 'up-to-date' it is. While there are actually companies out there that still use 50-year-old technology, they are few and far between. I used to pride myself on long uptimes. Then I realised that you have to reboot the system anyway if you want to upgrade the kernel or system version. That same thing applies to hardware. Can you still buy floppy disks, for instance? Maybe somewhere, yes. But not like they were available in every corner supermarket 20 years ago. CDs and DVDs, likewise. And what happens if you have all your backups on floppies (say) and you need to find a replacement floppy-drive just-right-now? It might be possible to build a server that will last 20 years, but would you want to stake your business or your life on it?
