The challenge is people find deep thinking uncomfortable. AI doesn't just replace thinking, it soothes that discomfort. It's less a tool and more a cognitive sedative. A comfort blanket for the brain. Feels great to externalise all that thinking. Too great! That’ll be a hard habit to kick for many.
Boiling here at home in Cyprus but I put the finishing touches a couple of days ago on this preprint: What Does 'Human-Centred AI' Mean? doi.org/10.48550/arX...
Wherein I analyse HCAI & demonstrate through 3 triplets my new tripartite definition of AI (Table 1) that properly centres the human. 1/n

One of these cult leaders had predicted that the "singularity" was gonna be in 2025. I think we all made it right? Barring anything happening in the next few days.
They'll update their so-called "calculations" (I.e. numbers out of asses) for the next "prediction."

Happy holidays! @jeffjarvis.bsky.social and I spoke with Ben Goertzel of SingularityNET on AI Inside about open source AI, regulation, and AGI’s messy middle. He argues “open” often stops at code. Two moments stood out.

When the people selling it are telling you they won’t stop without legislation forcing them to stop, that’s when you bring this quote to your lawmakers —as a parent.
