I haven't gotten into nfts myself but to say that they are stupid or a scam now comes across as wishful thinking to cover your butt for missing out.
nfts represent ownership over digital culture, like it or not. digital collectibles. the market will decide whether they are priced like banksys or beanie babies.
While many will be a fad, I'm certain some won't be. Other nfts will be as mundane as an event ticket. It's a wide open field, and I think the HN community should try to keep an open mind.
