I think it is easy for companies to waste time and money on lots of things when it is hard to measure the impact. For example, I think most people would agree that the big tech companies are bloated and have too many employees for the amount of work they have. There's not really an incentive to fix problems, and in some cases (like with headcount) there are counter-incentives (managers want to have more reports).
I think companies will get better at measuring the impact of AI and attributing it to increasing profit or decreasing costs, and that the companies that are better at this will have an advantage over those that are worse, so eventually overall efficiency will improve.
