The reason is very simple: developers don't want to develop anymore, they just want to offload real programming to third party libraries, where what used to take 100 lines of code to accomplish will take 10K or more (because, obviously, the library will do the most general version of what it wants to do). All this is considered "good development practices", which means that programs will inflate to take whatever memory is available and run slower for as long as we continue to use the same practices.
