When I'm running a lot of model training workflows concurrently, I can spend a small but noticeable amount of my day just clicking through links to see current progress and logs of any errors. If an AI would be capable of understanding the relatively complex UI, at least enough to find the right links to click, it could make a status report that takes me 15 seconds to read, and from that alone would save $2000 of labor annually.

I think their numbers of $1.6M and 3.25 years is still probably a massive overestimate, but the order of magnitude seems plausible.
