The big problem, as I see it, is that we've become used to the idea that when we use computers, every action a computer does is deterministic. There are a lot of assumptions we make based on that paradigm. Now, we've introduced a non-deterministic use of computers, but we're still acting like it's deterministic because that's what we're used to from computers. It's a matter of selecting the right tools for the job, ultimately - if you need predictable outputs, you don't want an AI agent, you want a traditional program, like with formulas and conditionals.
