Sure they do. All the time. They are mechanical devices with gears and wheels, like a pocket watch. Also, pitot/static tubes get contaminated, in which case a steam gauge or efis will stop working. So if you put in backup ASI and Alt hooked into the same pitot static lines, your reliability won't really improve. If your efis has a back up power source I bet it is statistically more reliable than an ASI, especially the cheapo Falcon ones.
There is a lot of prejudice out there, based on fear and superstition, but not hard data. "I feel more comfortable with X" doesn't mean X is safer.
Bottom line is, if you really want to be safe, learn to fly without ASI and Alt. It is not really that difficult. It was part of my initial training prior to solo. Personally I seem to land better without them. I guess I am more focused on visual cues. That extra half hour of training is cheaper than backup steam gauges.
