To play the devils advocate here (just for software), I would say principally this:

"A world where starting is incredibly easy and finishing is more complicated than ever"

LLM's do allow you to oneshot huge starting bits of work in record short time. The frontier of the amount of work they can oneshot is clearly getting larger and larger. But I am still not convinced that they allow you to maintain existing work at a cost that is below a human being.

But, if the frontier of what you can oneshot continues to grow unbounded, then it really will not matter. We will eventually oneshot all software and maintenance will be a thing of the past.

... But that is a very big bet.
