What an odd argument. Preparing food correctly will almost certainly be more reliable with machines.
Regarding the human element of dining: I think you lack foresight. We will look back at human waiters as we now look at horses, vs modern cars. People still ride horses, and that’s fine, but to suggest they’re the only way or even the best way to go is just archaic and indiciative of an unhealthy level of denial, or a calcified brain unable to change. Open your mind.
