Seems the scale of the store, the controlled supply of product, and the quality of tracking can essentially undermine most exploit vectors. Perhaps in a larger store, or perhaps with more crowds or variance in product... but as it stands, the Amazon Go store is about 1000 sq ft currently and it has been operating internally, daily, for over a year seeing hundreds of shoppers per day. I assume that if there was any issues they wouldn't be launching this publicly. I'm sure Amazon invites you to come and try to break the system, if you want. Edit: Other commenters state the sq ft of the store is closer to 1800, still very controllable.
