Uipath Task Mining: How good is the AI at finding tasks for an RPA

After watching some videos on YouTube I wondered how good is the AI actually at finding tasks for an RPA?
It sounds cool. You just let the task capture software watch your actions and the AI gives you ideas which tasks are best for an RPA. (If the system watched above 40k actions. The answers are better after 100k)

So has anybody here used the system? How good are the results? Did the system positively surprise you with the findings? Or is it just marketing?

Thanks
