The cash and reservation machines were definitively good examples because those things are simply obsolete. Paying through your phone or with a credit card (apart from tracking you mentioned) is easier and less expensive for the economy (more efficient) no matter how you put it, it&#x27;s just changing a few bits on some accounts. The same goes for reservations: when you have your smartphone everywhere with you and could do it from anywhere, a whole machine dedicated to it is completely obsolete.<p>Other differences definitively aren&#x27;t so clear. The trash is a good example, but a more glaring difference is how little crime they have. Crime is almost non-existent and there are no firearms, this can make parts of the US and large parts of the word seem comparatively barbaric.
