The benefit I'm getting is it stop almost all bots from submitting forms on my websites. It works basically flawlessly for that. I'm guessing you either don't run any websites with traffic or have never tried it if you think its worthless. I'm sure there are ways to bypass them but no one I care about has bothered so it doesn't matter. The lock on my front door doesn't have to stop a professional lock picker to be useful. The captcha on my website doesn't have to stop someone trying to get around it for it to be useful at stopping almost all the bots that don't even bother trying.
I literally am stopping bots though, it isn't hard to see the results or the differences between results into my systems with it on and off. It's weird that you're trying to argue against my actual experience.
Of course you do, you've managed to justify to yourself that your leeching is both giving it to Google and somehow supporting content creators. The internal inconsistency could only possibly lead to a good nights sleep.
