So I'd argue that being able to sift through 30 shots in 3 seconds isn't spraying and praying as much as it is being offered the job to make a better selection to settle on.
High tech gear certainly is awesome and convenient, but I'd argue the gear still needs a photographer. Sports and wildlife photographers did learn to get very good shots in the old days, one shot timed by eye, or natural instinct really. Water drop splashes are much harder, easy using a timer, but some even do that by eye. Trial and error is always involved, but it seems largely dependent on trying to learn. Ten frames per second does not seem even influenced by the photographer, and sure does sound like spraying and praying. My notion is that complaining it can't be done with less than 10 frames per second is just the poor worker blaming his tools. Others certainly seem able to do it with less.
