Belt drives are fine, but I don't think they're really the improvement over chain drive they're touted as.[0] If you really want reliability out of your bike, they're both sensitive to dirt and grime and benefit from a full chain case.[1] Definitely a fan of internal hubs for commuting, but they're usually at least an order of magnitude more expensive than derailler systems. Both enclosed chain cases and internal hub gears have been around over 100yrs though, almost from the beginning of bicycles. Surprised it took so long for tubeless tires and disc brakes to become popular on bicycles since they've been used on motorcycles and cars for many decades. Otherwise the "gold standard" fancy bikes still exist and still look closer to a bike from 1900 than most bikes on shelf do.
