Eh, I think you're being too hard. Although PCB tools might be different, as far as IC design goes, most of the problems at the earlier nodes were solved by the EDA companies throwing legions of (very expensive!) PhDs at the problem. I do agree that some things are annoying, such as documentation and UI, but a lot of this is because (scarce!) money is prioritized to solving problems and fixing bugs and they don't want to take a chance destroying the system. In particular, major customers tend to be extremely risk averse.
