Wrappers around LLMs promise to bridge that gap. I'm sure it can do well for the vast majority of cases. But I do wonder what the outliers would cost.

E.g traditional automation + humans handling the drag = $4,000 per month with a couple of known blunder each year

vs traditional automation + AI = $400, with unknown number of blunders.

Of course it depends how much a blunder costs, to solve, or swallow. But I would bet that accounting errors even for a small business would cost the business on the long run. And that's assuming we don't yet have adversarial behavior which we can expect to come from both the inside and the outside.
