I don't see how that contradicts the parent post. Computer vision wasn't as good when reCAPTCHA was still typing out books, but machine learning has (per my expectation, having worked with it since ~2015, but the proof would be in the pudding) likely been good enough for mimicking e.g. keystroke timings for decades. It hasn't been needed until now. That doesn't mean they won't use it now that it is needed. Different situation from where tech did not yet exist
Section 3 anticipates and addresses this objection.
The ultimate challenge is to replicate end-to-end natural human cognition, which is currently an unsolved and hard problem (and also not necessarily the main focus of AI researchers).
