I stand corrected. You're almost right, I should have said 4 billion, I remembered the number as 4-something. You can see at 1:16 in, the ARC pilot says 3,000? M$. Without going through the whole video again, I'm almost certain someone during the discussion mentioned 4 billion. You're right thought, a proof of concept can be done for an order of magnitude less.
