You extrapolate from current machines. I do believe that AI-assisted companies will build AI-assisted always-online machines that will be worth their money, no need to hack. I imagine a $25 Starlink subscription for a John Deere fleet of autonomous tractors that work through the night will replace what we have now.
(to stay within physical machinery, like the post.)
john deere machines have been doing very well without llm
actually I have no idea what would llm do to make their machines better
