As part of this fascinating conversation, Roger Penrose implies he tried to get Douglas Hofstadter to claim some integers are conscious, and DH was open to this (hmm). I wonder how that argument would go if they met today. That would be a podcast I’d love to see, @curtjaimungal.bsky.social.
Sir Roger Penrose: “People say quantum gravity is the big mystery. The main mystery is the gravitisation of quantum mechanics.”

Do you agree?

Does the word order matter or is it negligible?

“No man is an island,
Entire of itself;
Every man is a piece of the continent,
A part of the main…

Any man's death diminishes me,
Because I am involved in mankind.
And therefore never send to know for whom the bell tolls;
It tolls for thee.”

In one of the best discussions on computational functionalism v biological naturalism (relating to consciousness), @anilseth.bsky.social considers various arguments, including the Brain of Theseus/neural replacement. Frustratingly, he says, “You can’t really do that” without explaining why.

Day 1 of the #NaturalPhilosophy Symposium wrapped up with a panel discussion from the day's speakers: David Chalmers, Sandra Mitchell, Nima Arkani-Hamed, Kevin Zollman, Malcolm MacIver, and Nick Lane, moderated by Chanda Prescod-Weinstein @chanda.blacksky.app.

DNA sequences are computer code! It was a pleasure to explore John Von Neumann's theory on life as a form of computation and the lessons we can learn from modern AI systems with Tim Scarfe on Machine Learning Street Talk: bit.ly/4nreMO7

Thank you for the thoughtful questions!

Scientists are levitating tiny glass/diamond spheres, cooling them to near stillness, then putting them in quantum superposition (two places at once). They drop them in freefall to test if gravity entangles those “ghost” versions.
Yes: gravity’s quantum. No: It’s something else.

I’m fascinated by the ideas of Donald Hoffman & Michael Graziano. They seem hard to reconcile: Hoffman pictures a single consciousness beyond spacetime, Graziano says consciousness is modelling where the brain’s attention is. In a metaphor, does G explain the window & H the viewer?

“We live in succession, in division, in parts, in particles.
Meantime within man is the soul of the whole; the wise silence; the universal beauty, to which every part and particle is equally related, the eternal ONE.”

How close are we to building a quantum gravity computer to study consciousness?

“We’re not actually building animals, we’re building ghosts.”
@karpathy.bsky.social on LLMs.

Do you agree?

Do you think AI will solve the Riemann hypothesis? Why/why not? If yes, how soon might it be?

Professor Takashi Ikegami is combining robots with LLMs to create embodied AI. Just as LLMs can create pictures out of pixels, the movement of the robots is sort of pixelated in a similar way, so the LLM can control 3D actions in the real world.

“For most of us, there is only the unattended
Moment, the moment in and out of time,
The distraction fit, lost in a shaft of sunlight,
The wild thyme unseen, or the winter lightning
Or the waterfall, or music heard so deeply
That it is not heard at all, but you are the music
While the music lasts.”

Fascinating conversation between @suzannegildert.bsky.social & Tevin Naidu.
Suzanne pictures minds as bubbles connected but separated. They pop or join a larger bubble but lose individuality as they are absorbed. Reminds me of Thales’ ‘everything is water’ or that minds are icebergs/waves.

I like using Bohemian Rhapsody's screwball transitions to illustrate the need for a notion of identity as 'processual continuity', rather than 'preservation of invariants'.

So its cool to discover music modellers analysing this as the "Bohemian Rhapsody problem" eceweb.ucsd.edu/~gert/papers...

“You won’t lose your job to a tractor, but to a horse who learns how to drive a tractor.”

This is such a funny (and insightful) take on the, “You won’t lose your job to AI, but to someone who uses AI.”

I wish I knew who to credit.
