This is warm-and-fuzzy sounding sophistry. JFK didn't just say, "Screw it we're going to the moon." He put billions of funding and hired smart people to do it

This is warm-and-fuzzy sounding sophistry. JFK didn't just say, "Screw it we're going to the moon." He put billions of funding and hired smart people to do it. The bad things that will happen to you is typically not an irate man shipped to you in a box. The first rule: don't lose the principal. That is, don't do stupid things that will get you hacked, whether the loss be small or large. I don't understand the necessity of QR code for a URL, they are worse than URL shortener. Is there an actual, valid, use case of QR codes, I can only think of 2FA key generation, and even that could be done pointing your camera at a string of digits? With OCR, you and your phone can see where you're going. Nobody is stopping you from going to fun, unsafe places, don't get robbed doing it, that's all we're saying. Edited to add: I think what made the QR code take off was restaurants putting them on their menus in the pandemic, so they could do touchless, menu-less ordering. Their ubiquitousness and the harmless environment in which they are encountered (restaurants, food, drinks, friends) acclimate people to using them and formed a habit and a perception when there had been none. It's not a new danger; unsafe URL had always been a danger, now it has a new benign look.
