Well, yeah, I'm just saying it wasn't a picnic at 40nm or 90nm, either. It didn't go from a walk in the park to a nightmare at 28nm.

Also I believe all the bugs in TFA are logical bugs where the circuit would have misbehaved in a logical simulation, not the kind where the circuit "flips zeros to ones" or vice versa because of physical implementation issues. In this sense advanced nodes make things worse only indirectly by enabling larger, more complex designs.
