It seems everybody is talking at a different level of abstraction. Reality is complex so the closest you're to it, the more complex your code will be (e.g. kernel supporting a zillion different hardware devices).

If the idea is to abstract even more in a simple and powerful way that more people can create more/better software, go for it. But don't dream that all that has been done until this day is complex because nobody cared about simplicity at all. I'm not saying the complexity is completely unavoidable but it takes a lot of work.
