The rate of output from LLMs is very high compared to most developers' capacity to review every line, especially when they are often working on multiple tasks from multiple projects all on the same day. The directive to increase code churning is coming from the top since upper management believes everything tech CEOs advertise to them, and there is increasing anxiety across tech, mathematics, finance, arts, etc. about getting replaced so people want to at least appear to be much more productive with AI. The new norm is fast becoming "There will be mistakes, but maybe not most of the time. We'll deal with it when we get there, and since we're all on the same boat, let's spread out the blame or try to ignore it since you never know when it might happen to you."

To be fair, this was always the case as there was never any guarantee of bug-free code in general, but the difference today is mainly in volume.

Yes, they do.

But this problem goes far deeper. People that hire someone else believe they have outsourced the responsibility, and not the work.

What is "taking accountability" supposed to look like in this case?

As an aside, trying to enforce some cultural more without the backing of senior leadership is a waste of time. You should probably follow your colleagues example and get a better return on your time with Claude and stop caring. If you are the only one at your company who cares and you aren't the largest shareholder I have to ask under what economic theory you are operating. Unless you work for a charity or something you should probably either find a new job or stop complaining about the relative luxury of being handed a fistful of money just to be able to say "Claude wrote that".

Apparently no one at your company cares, so why do you?
