@oldgodspod.bsky.social love the show! so apologies if this has already been answered, but do you see vamps as creatures of the Black or Green? I would’ve assumed the former, but then those beneath might already have some.

Thank you for your attention. Am wondering why you haven’t yet also targeted @royalsocietypublishing.org in which the study I wrote about ran, or @edyong209.bsky.social given his NatGeo story, or @rachelnuwer.bsky.social given her Smithsonian piece, or the study’s authors? Why am I so lucky?

In the Disney lawsuit, 10 pages are dedicated to citing the work we did. In pursuit of this evidence, Midjourney banned me 3 times and updated their ToS. The first ban encouraged me to dig a lot deeper, so I'd like to congratulate CEO David Holz on his massive unforced error.

🔥 It's happening! Disney and Universal are suing Midjourney and they cited mine and Gary Marcus' work exposing their infringement in their filing. LET'S GO! 🔥

“We did not publish a paper.. on this topic with that co-author group, or with that title,” says one cited researcher.

Why create an AI model of a fish? New research from our own Nate Sawtell & Larry Abbott, along with Denis Turcu, shows how real fish can use electricity to scan the world, findings that could help us understand our own senses, such as vision:
