Yeah, that's one part of this that didn't sit right with me.

I don't think you need to spend anything like that amount of money to get the majority of the value they're describing here.

This is the part that feels right to me because agents are idiots.

I built a tool that writes (non shit) reports from unstructured data to be used internally by analysts at a trading firm.

It cost between $500 to $5000 per day per seat to run.

It could have cost a lot more but latency matters in market reports in a way it doesn't for software. I imagine they are burning $1000 per day per seat because they can't afford more.

I wonder if this is just a byproduct of factories being very early and very inefficient. Yegge and Huntley both acknowledge that their experiments in autonomous factories are extremely expensive and wasteful!

I would expect cost to come down over time, using approaches pioneered in the field of manufacturing.
