I don’t think you can in good faith compare…
Ooh, that’s just one of my pet peeves. Such a stupid fucking phrase. The only way to know if you “can’t compare” two things is to do a comparison between them and come to the conclusion that the two things are very different. I can compare self checkout to a kumquat if I want to.
Now for some actually useful conversation, let’s compare number of steps for vending machine vs self checkout (since that’s the closer of my two examples).
Vending machine:
- insert payment
- push button to select items
- pick up item
- repeat all steps until you have the number of items desired
Self checkout:
- scan item or place item on scanner/scale and push buttons for item type. This only counts as one step, because you are never doing both to the same item
- repeat first step until you have all items desired
- insert payment
- pick up items
It’s the same steps in a different order.
Re-invent. Your still far too late to be first.
