In a digital world, everything is either on, or off. Modern electronic system? On or off....fueling? On or off...mostly binary events.
Carbs, points have no on/off...just an area where it runs poorly, but gets you home....you might limp there, but it works, even poorly...poor running tells you to check it out and adjust it back at the ranch...you might not leave the ranch because your analog bike is telling you something is amiss...
Digital binary events all around us....that can't be McGiver-ed to get it to run...just a system that goes off when it fails....battery, ignition, fueling, trip to the dealer to diagnose...
Yes, the failure rate is lower, but it gives no warning signs....zap, your walking with no options for self sufficiency
