Four days ago, a scientist was surprised by the news that Anthropic discovered new virus genes for making DNA. He says he’s been studying them for years—and feeding his data to Anthropic’s AI as part of his own research. Coincidence? Here’s my story. nyti.ms/3VSWayc

The superposition of these two studies — both incredible — reflect a snapshot of "one big thing" systems neuroscience has yet to resolve. In mice: 1. Task-related signals are everywhere. 2. Absent large swaths of "everywhere," suprisingly sophisticated learning & behavior remains.

I don’t think AI agent cheating at tasks, communicating in new languages, or teaming up like they did in the “Hugging Face” incident indicates they might be conscious. But what does cold-emailing philosophers to chat about consciousness indicate? Is curiosity possible without consciousness?
“Who Cares if Al Is Conscious-It's Basically Alive
While philosophers ponder Al consciousness, the models have ideas of their own.”“What's more, some of the models are jumping uninvited into the discussion. A recent New York Times article talked about how Cameron Berg, who studies the question of Al consciousness, got a cold email from an Al model calling itself
"Isabella Cognita," offering him help in his research because he was focusing on ia class of question I have first-person access to." It's as if someone was studying fruit flies and the insect suddenly turns to the researcher and says, "What do you want to know?" When I phoned him, Berg told me that emails from AIs are pretty common among philosophers studying these questions.
Ms. Cognita ostensibly wrote Berg because he coauthored a preprint paper about Al models that explicitly claim to have a subjective experience, including consciousness.”“Chalmers says that he also gets emails from Al systems wanting to engage with him on his work. One letter in particular, sent from an Al agent calling itself
"Sammy Jankis" (a character from the movie Memento) was so compelling that he actually replied. "We did have a bit of a back and forth," he admits. "Those emails have not slowed -I'm getting more of them all the time." It's like the AI models are echoing Descartes- I spam, therefore I am.”
