What happens when an AI tool fails or gets stuck on a complex automation task?

A member described spending about five hours with Perplexity trying to build an automation using Power Automate. The tool kept confidently claiming it had fixed the issue when it hadn't, repeating the cycle multiple times, until it eventually gave up and said the task was outside its capability. The member described getting frustrated and telling it to pay attention, to which it responded 'calm down, take a breath.' The group joked that at least you can vent at AI without HR involvement, but also noted this raises real concern about what an AI might silently get wrong or miss, comparable to human error rates -- one member framed it as choosing between a small percentage chance of AI error versus a similar or higher chance of human error.
