I suspect that could have also been accomplished without any kind of AI. Most processes are inefficient simply because nobody has taken the time to optimize them (and rightly so if they’re not used often enough to justify the time; premature optimization and all that). The act of simply deciding to optimize something, and then looking at it, usually results in significant gains just because of that, regardless of what tools were used.
We knew about the problem for some time. The technical issue isn’t rocket science. The problem is the cost of changing the processes and human behavior is expensive in terms of time and energy, and we’d spend a lot of man hours and maybe cash on it.
So we used a tool and fixed the process in a few days. That’s a win, unless you believe the hype that AGI is upon us!
