You 100% can write them off entirely and go about your business as you previously had done. Ignoring the errors, it is very debatable whether there are even productivity gains beyond: human programmer or whatever is excited and cranked up to unsustainable degrees of activity and thinking to 'keep up' with what he thinks is an AI doing the work.

I'm seeing this fairly often and when it isn't garbage it's a capable person who has gotten inspired by their 'collaboration' in which the busywork is being done by a machine, but they're doing so much directing and correcting that it's not unlike what would happen if they got heavy into meth and went on a tear.

You absolutely can write them off entirely and decide for yourself what your comfort level of human-killing speed-freakism you want to pursue in your productivity. There's a long history of humans managing astonishing levels of productivity through self-destructive means. This is not even cheaper, once the 'first one's free' wears off: it's just a novel method of getting humans to burn themselves harder in the belief that they have a magic feather.

The ones who're really throwing themselves into the situation are the ones who'll burn out, but who aren't setting themselves up for atrophy and learned helplessness. Anyone who believes the technology lets them be a lazy manager just getting paid, is in for an unpleasant discovery.
