PCB routing is generally considered a much harder problem. There are a bunch of reasons that add up, but one of them is almost certainly that a PCB is supposed to look good too. The routing on an IC is total chaos (which actually reduces crosstalk issues), but nobody will ever notice.

That's an interesting point
PCBs "look good" because of different production contraints (and I guess because you're mostly connecting tight-timed busses together)
In ICs you're doing the above but also pulling signals from 10 different places together.
