Is it just closed source software that does this? With a lot of the big open source projects one can expect incremental speed improvements with every release (although this is far from guaranteed). My LAMP stack is quicker than it was a few years ago, not slower. With my own coding efforts I consider bloat and speed to be really important. Slower is not better unless there are some major features that have been added and not refactored yet. At Apple do they just go anti-pattern? Define the array inside the for loop rather than just do it before entering the loop? Maybe when iOS 15 comes along someone will put iOS 9 on it somehow and it will blaze along. I doubt it, but I would not be at all surprised if the delays in opening apps are the same in iOS 15 and the hardware that goes with it. There should be a 'Moore's Constant' for this, to describe how all advances in silicon are instantly negated by operating systems at boot time to have a consistent amount of delay when opening apps.
