This is crazy awesome! I just wanted to do a cost breakdown:
0.6s/$ is $6,000/hour (thanks @danielvf).
The excavator is around $2000/day[1].
The truck is around $2200/day[2].
Plus at least two operators with $200/day each[3].
And then the cost of Stripe's fees, buying the land, getting a permit (?), etc.
