BF's son just got qualified on the 737. He came off of the CRJ-200/700/900. He's very impressed with the ability of the automation and autothrottles, VNAV/LNAV, but didn't realize how much the workload was to adjust to it. As a jumpseater he'd watched guys who were fully up to speed on the automation who made it look easy. Now that he's in the seat, versus observing from the jumpseat, he's realized the learning curve is steeper than he realized despite having watched it numerous times.
