OK, so don’t buy their PR, and try it yourself.
But if you do this, you will find there is a lot of evidence for the economic argument.
I tested out Google Argon 4 release by having it build a Web app to replace a binder I have for reconciling payments with reimbursable expenses.
It did it, as well as I would have and in much less time. I just set it to high and supervised it, it cost about $2. Even if you throw in a “supervision cost” to account for the time I had to spend interacting with it, it was substantially cheaper than had I done it at normal salary rates. Probably 2 orders of magnitude cheaper, even.
