Doing a few rounds of these with a site. I'm pretty convinced any modern AI can do it 10x faster than I can

(*finds fire hydrants for nth time*)

I suspect there's also hidden parts of the challenge, like having a "realistic" mouse movement pattern. Though AI can probably ace that too.

AI can handle this task using machine learning techniques and behavioural imitation based on data about real mouse movements. Some bots or automated systems do use such ‘human’ patterns to bypass security systems that may recognise artificial, overly precise movements. This is important if the task requires mimicking real user behaviour.
I wonder what you think about how AI can handle such hidden tasks?
