Very little code written in the world day to day ever has to justify its 'quality' or long term value. A lot it is just one off tools, bits and bobs to make a teams life easier or whatever.

I used to work in Web agency for sizeable brands and not a single site I built lasted over a year because the companies changed concept regularly. The next agency would come in and tell them it was built wrong and couldn't be reused etc etc. We did the same, it was irrelevant how it was built and we didn't even look. This is the nature of most code. The problem is that very few people will ever be in a position to be writing verifiable important code, but every developer likes to cosplay that they are.

Most code is ultimately an, annoyance businesses need to meet a goal that will always be a cost. It's often worth treating it as such and writing things that are easy to spin up and teardown.

The people most vexed by AI dev appear to be the ones who think writing code is a pinnacle role, it's not even though over our lives the salaries would sometime suggest otherwise. That's ultimately going to be a short term blip in the landscape and most code will be one seen as the cost it is.
