I would believe we are headed towards a cashier-less store too. Our local Walmart store removed cash registers and set up at least double self check out aisles, if not triple--and right before Christmas! I wonder how much $$ they will save during the holidays.... It's inevitable. Computers are high tech these days--not just desktop or laptops anymore--with AI robots that can 'learn' from us, carry on conversation & remember it, even asking more questions to keep the conversation going! It's unreal how far we have come in AI in recent years. It is no wonder we are moving forward with robots and they are advancing so quickly.
