Still, software is slowing down. Anecdotal example: my phone. It used to run fine at the beginning then now a few years later everything is slow: Google maps, YouTube, Signal, the pin-code screen… I barely have installed any apps, the only thing that changed is the number of messages I have and the updates.
Perhaps we could justify it with new features at least? Perhaps my phone is slower now because the things in there are so much more useful now? Well, no. I got maybe a couple cosmetic changes, but functionality is exactly the same. My phone got slower for no benefit.
