Here’s a case where it would make sense to replace the phrase β€œArtificial Intelligence” with β€œnot-very-well-understood computer programs prone to unpredictable errors.”

Thank you for these references.

Why is that? Does the language use here affect how we allocate resources (e.g. to drug development vs. prevention/detection) or something?

Here's the cover of my upcoming book, Cyborg Rights (Routledge), that explores how extension technologies like brain–computer interfaces challenge mental privacy, mental integrity, and the nature of personhoodβ€”through the lens of the Extended Mind Thesis.

What is an "algorithm", and why is this basic notion in CS and math still so difficult to define? Do we use a consistent idea of algorithm in these fields? My paper on these issues and the conceptual dilemmas faced in trying to develop a definition is now out. Link below.

Great episode (as always). BTW, the case for geometry's origin in our embodied nature has wonderfully and lucidly been made by PoincarΓ© (e.g. in his "Science and Hypothesis"). In his apt words "if there were no solid bodies in nature, there would be no geometry".

Beyond that though, I have been doing this sci comm stuff for a long time, and I have NEVER before known a time when I've had to grapple with so many nonsensical claims from tech leaders. There's just a constant stream, which most of the media gobbles up. I'm frankly really tired of it. 9/9

Trump says "Russia made a mistake" bombing the Palm Sunday service. We were aiming for the local hospital instead which he's ok with.

Needless to say that it also has some tiny amount of consciousness, right?

Yes, everything. Including my pipe right now. (Too bad I have no clue how to use it to compute my share of the restaurant bill).

Story about Russia's human rights commissioner (if you can imagine such a thing) talking about Prisoners or war in something they insist is not a war

Story about Russia's human rights commissioner (if you can imagine such a thing) talking about Prisoners or war in something they insist is not a war

2 points:

1 If you ever feel your job is completely pointless, consider that the Kremlin employs someone to be a "human rights commissioner"

2 POWs? Prisoners of War. WAR?? YOU'RE NOT SUPPOSED TO ADMIT IT'S A WAR YOU IDIOTS!!!

ChatGPT. But only for language editing and condensing my paragraphs (when I'm facing a word limit). I have not found it very useful for other tasks.

Yes, please do! Your posts, and the "joy of whyβ€œ podcast are so much inspiring, especially for young researchers!
