That probably was exactly her point. While good engineers simulate _critical_ portions of their designs (should such portions exist in that particular design) , there's no need to simulate the whole schematic. Moreover, you stated that "with experience you learn to recognize which portions merit simulation" . The logical continuation here is that you also learn which don't warrant a simulation, and they're a lot more than the ones that do. The "no simulaiton" category is also growing with experience , so you simulate less and less of a design due to 2 factors, you both 1) learn to recognize more accurately what is really critical and 2), you learn solutions and already implement them for high sensitivity circuits from the schematic capture stage , which you also recognize due to experience. I've seen so many poor circuits due to inexperienced designers, like single ended stages where differential should've been a given, poor supply noise performance, high jitter, and they were coming from clueless engineers. All with lots of effort put into simulation , only simulation of useless and obvious features . The ones the clueless guys were capable of foreseeing .
