The same way niche/luxury product and services compare to fast/cheap ones: they are made with focus and intent that goes against the statistical average, which also normally would take more time and effort to make.
McDonalds cooks ~great~ (edit: fair enough, decent) burgers when measured objectively, but people still go to more niche burger restaurants because they want something different and made with more care.
That's not to say that an human can't use AI with intent, but then AI becomes another tool and not an autonomous code generating agent.
> McDonalds cooks great burgers when measured objectively
Wait, what? In what world are McDonalds burgers "great"? They're cheap. Maybe even a good value. But that's not the same as great.
They are consistent and decent, though arguably some are even good (though everyone usually has a preferred fast food destination).
Some of the best burgers I've ever had came from fast food.
Probably more of the measure of the Deluxe burger, which if fresh doesn't seem to have any faults for a burger. Now the little McFrankinstines leave much to be desired.
Fair enough, I should've said borderline decent.
