It's quite likely they are quoting the actual costs from 2 different car plants.

(that would make them highly task specific, but it would reflect the difference in welding costs for producing cars on a high volume line)

I checked linked study:

> A human welder today earns around $25 per hour (including benefits), while the equivalent operating cost per hour for a robot is around $8 when installation, maintenance, and the operating costs of all hardware, software, and peripherals are amortized over a five-year depreciation period.

So human cost does not include total cost, just labour. Comparable cost would be around $100
