I am, but what I said was more of a hypothesis than a fact :) From what I understand of reCAPTCHA, the model isn't static and is continuously learning from every interaction[0]: > reCAPTCHA’s risk-based bot algorithms apply continuous machine learning that factors in every customer and bot interaction to overcome the binary heuristic logic of traditional challenge-based bot detection technologies. I don't know the energy demands of such a system. mCaptcha, under attack situations, will at most take 5s of CPU time on a busy (regular multitasking with multiple background process) smartphone.
