An impossible computer is different from a computer that humankind can not yet build. If our universe is a simulation, then some entity has already proven you wrong. If our universe isn't a simulation, our limited resources prevent us from running (detailed) universe-scale simulations. I'd say that we will eventually be able to simulate a drug interaction from these rules (it's the interaction between these rules that's the key) but I won't predict WHEN that might occur.
