I don&#x27;t buy the argument.<p>That&#x27;s like saying, I have a 1TB hard disk.<p>Now I have less files, so I can save money by not upgrading.<p>Sure, you might not be forced to upgrade due to space constraints.<p>But harddisks are mechanical devices - they degrade over time (just like trains, roads, plumbing etc.). If you don&#x27;t replace your harddisks for 10 years, because you somehow manage to delete a bunch of files, and not replace them ....well, good luck trying to access your data.<p>Also, technology is constantly evolving - and trite as it may sound, if you&#x27;re not going forwards, you&#x27;re going backwards.<p>Have you tried using, oh, say, a Quantum fireball drive lately, to run a modern operating system or modern applications?<p>I mean, apart from the incompatibility issues, even if you got it running, and even if you managed to fit it on there, it just wouldn&#x27;t be able to keep up.<p>So no, having a falling population doesn&#x27;t mean you can just sit and let your infrastructure run into the ground.
