It's not that they didn't block UV, it's that they installed UV lights in the DJ booth because it would "look cool".
It was a purposeful choice, and no one stopped to think about why it was a bad idea. Which is totally on brand for people running a convention based around NFTs.
I saw a case of this in a documentary, a club installed 'pretty' powder blue UVC lights everywhere and it crisped up the attendees. The UVC part of the light doesn't register to your eyes, so your pupils stay wide open and the designers added tons of it because it wasn't that bright.
They used the wrong type of bulb. Ordinarily the bulb will be made of a UV blocking glass, and not be quartz based. I think? So it’s not usually the shroud that stops UV except in cases of Halogen bulbs. These would be CFL without any shield except perhaps a cage to protect against things thrown.
Laughing at these people for getting their retinas burned like I see many people do (not just here) is in really bad taste imo. Even cryptobros don't deserve that.
It's temporary arc flash from UVC exposute, it's extremely unlikely that any of them will suffer long term effects. Just feels like sand in your eyes for a few days.
It's more likely to be down to incompetence. I can't imagine the party UV lights are more expensive than the fuck-you-up UV lights.
EDIT: Someone else mentioned these might've been used during COVID for sanitation, and are extremely cheap leftover wares now that the pandemic is "over", which would actually make them a lot cheaper.
Never attribute to malice what can be explained by plain incompetence is a saying. But I think a new modern corollary can be made. Never attribute to incompetence what can be easily explained by greed, which just circles back to malice and is stupidity at the same time.
To be fair the idea behind nft’s is great when its about tracking a commodity, item or piece of information.
Its making them “THE” commodity that is cringe levels of stupid.
I still hope that one day press will have professional onlines cameras generating an nft with location, time and camera id for every piece of footage. No more fake news with misused imagery.
