I'm not sure what you mean by "big bang approach". There isn't a single company whose goal is 100% or nothing. Not cruise, nor waymo, nor anyone else. That's why they have things like remote assistance and incremental rollouts. Similarly, waymo and cruise are both making [small amounts of] money on their "intermediary" robotaxis right now.

http://www.paulgraham.com/aord.html is contextually relevant to the point you don't understand the meaning of. They are operating in an abstracted representation of the situation related to what Paul Graham talks about. In that abstracted representation you get some not so obvious corollaries: a deep relationship between confidence and the reasonableness of default alive versus default dead strategy.
