Presumably something like the 'commoditization of elevator operating' that we once saw. The elevator operator never went away, but operating elevators was simplified to the point that anyone could do it. At which time everyone started doing it, commoditizing the job.
In other words, it looks like programming languages that become increasingly approachable to any old random person on the street who can jump in without any meaningful past experience or special knowledge. You know doubt already what that looks like because we're already using those programming languages (e.g. GPT) in narrow domains to great effect. They have yet to prove themselves as complete general purpose programming languages, but they have made great strives towards that and it is, by many accounts, now only a matter of time.
