In a new stadium in my city you swipe your credit card, pick up food or drink in a little monitored area and walk out with your items. It is an interesting idea but it is also creepy. That's probably what stores will be like eventually -- at least the ones with the resources to implement something that expensive and complex.
As far as self checkout, I don't mind it for small orders or when it is more convenient for me at the grocery store. Unexpected item in bagging is a bad consumer experience, and buying produce/alcohol is also a pain. If I feel like I am going to run into trouble I head for the traditional lines.
I really despise the ones at big box hardware stores that show a video of you checking out. I'm not stealing, don't judge me or make me judge myself with that unflattering angle.

The only time I used one of those was at a conference center and I was trying to get a cheap lunch. The item I wanted was out of stock in the computer system so it wouldn't let me purchase it and the item I grabbed was charged as something else entirely (netting me a $3 discount at least)
Vending machines have been around for years and their faultiness has long been a trope in media. I'm not holding my breath for employee-less checkout
I go to the cashier's and try to never self checkout. It has always seemed like a way to reduce the number of employees. The price of goods sure hasn't gone down as a result. People need jobs. These stores are rich enough. I realize that's a little naive but that's where I am with it.
I'd always rather shop at a store with real life helpful employees who are happy to work there because they are treated well and properly compensated. I hope companies continue to see the value in that approach.
