Just to add some more context, these were used back in the day at chill areas of hacker conferences.
Back then wifi (if available) was not very reliable, and battery tech less advanced.
People carried network cables and extension cords in their backpack.
I struggle with that comparison, but it sounds like the sports car guy feels that his conspicuous wealth should elevate him above the rules meant for everyone else. To the extent that he shouldn’t even have to ask for it out loud, because his car is art and yours is a commodity that makes no statement on the scarcity of beauty.
If NFTs exist to make an artistic statement, then it’s not the same as a one-off art car. It’s a statement on conspicuously raising the ecological and conceptual cost for the same vulgar image that any scrolling rube can enjoy.
An NFT really could represent season tickets for some assigned seats in a sports arena, or (unfortunately) the order on a list of organ transplant recipients. But instead of problems of scarcity, NFT represents FOMO. And the most-confident adherents are definitely speculating on riding the wave.
It depends on the qr-code scanner you have on your phone. The one on my android shows a button 'connect to this network'.
In regards to security, you are completely correct. But this is to be used in cases where one would put a paper with the password on the wall, think of coffee shops. Saves some typing. Or you can put a card on your coffee table to help out your house guests.
