...I like the Kalman Filter even if I might not be quite up to programming one. Every time I drive a modern car with a shitty automatic transmission that glitches and stutters and fails to shift right, I think "Is this thing using a Kalman filter, or what fundamentally wrong thing was done with the programming here?" I wish someone would reveal to me whether the algorithm is not the panacea I wish it were, or else what a lousy programmer does when they don't know about it.
