Sex robots. Sorry, just can't do it.
Beyond that... Nobel laureate Arno Penzias spoke of the phenomenon of "running errands" on behalf of your computer. Traditionally, BPM has been good at handling exactly the kind of tedious, unnecessary human action to which Penzias was referring: entering data that could be obtained automatically; tracking on-time statistics; determining who is next in line to act in a process.
Now that BPM is much more sophisticated, can it go beyond the errand-running stage? Of course. Intelligent, automated decision making (sorry, I refuse to use "decisioning
") takes the necessarily arbitrary dimension of human judgment out of the loop where it is not really needed. And, as we get better at processing and interpreting large amounts of data, that decision making can only improve.
At the end of the day, though, at some point you need a human to decide when it's OK to push the button. ...not that that always turns out so well either...
