“We trained weasels to count how many customers came into the store” - reasonable; unproblematic; probably a thing you could do.
“We trained weasels to screen resumes of people applying to jobs” - probably a bad idea, especially if the weasels are racist or sexist (the weasels are both racist and sexist).
“We trained weasels to drive a two-ton vehicle on busy city streets” - terrible idea; someone is almost certainly going to die.
