Why shouldn't those things be easy? Wouldn't it be better if they were? It would mean more people could do it well (I'm not saying let anyone do it!) and it would presumably have come about as a result of better understanding and tooling. Imagine if people didn't die on the waitlist for the best neurosurgeon in the country, because we'd made brain surgery easier and so now all the neurosurgeons could do that one formerly-super-difficult surgery.
