Indeed the initial capital needs to come from somewhere, although I will argue that technology creates a deflationary spiral allowing automatons to be acquired cheaper than traditional tooling.

"The students involved in the Hands Free Hectare project also suggest that this was probably “the most expensive hectare of barley ever,” with an overall budget of £200,000 from the U.K. government.
