How can we test for consciousness in infants, non-human animals, and AI? I'm super happy that the recordings of our last workshop on exactly this question are now online! Speakers and links to talks below! 👇 #ConSci

I have a lot of pretty nasty thoughts about the "first AI philosophy" essay competition, but I'll restrain myself to saying that it'd be nice if philosophers stopped bending over backwards to get the attention of big tech companies...

Timely again with the recent open letter. I support disclosures (of course) but the deeper problem is that the current publishing model is incompatible with pervasive industry ties.

Philosophy's traditional model - highly selective journals, tough "reject for any reason" peer review - assumes that no area of the field is pervaded by conflicts of interest. It's clearly an unsuitable model for philosophy of AI, where industry-funded research is already starting to dominate.
