To each his own, I exclusively use the self checkout line whenever I can (especially at costco) and it saves me a ton of time. Besides the point here was about innovation and working towards a better future, which the amazon cashierless stores might be. Just because the current solution for self-checkouts is bad doesn't mean we should stop innovating.
Working towards a better future sounds like an admirable goal, but that's ad-speak on top of actual goals of the innovation, which is more profitable retail.
I don't personally think a robot grocery store is something I'm interested in, but that's entirely subjective.
