There's a difference between the cost of coding and the cost of delivering and maintaining software? AI has demonstrated that these two things are almost entirely unrelated.
So, AI is making 5-10% of your project much faster. Whoopdie doo.
The firms of 2031 won’t be doing business like the firms of 2021 but just using AI for coding or in a few places to accelerate the same workflows.
I think it sums up to something along the lines of "you get what you pay for".
