Obvious answer is: any control system connected to a computer is already accessible. Who says a computer program has to "gain" access? Programs already have access to a lot of machinery. From power plants to hospitals to elevators and magnetic doors. I know, because I programmed a bunch. These days GPT can output function calls as json, all you need to do is make it call your control automation and all your cheesy unrealistic sci-fi shows become feasible.
