The point of spending this massive amount of money on an automated store is to recoup that investment by opening lots of automated stores and make money in volume, taking advantage of your lower labor costs.

If they don't actually open at least hundreds of these then they've thrown away massive amounts of money on R&D they'll never get back, and the data they did accumulate isn't even particularly useful as it's in the context of a type of store they're not running at scale.
