Science is a cultural institution that allows our species to directly confront our epistemological limits. It’s easy to think the criticism & controversy in science is the eclipsing battle but the only battle that really matters is the one at the boundary of what we know

Spontaneous, infinite physics leaves life without definition or meaning. Finite, recursive physics makes life definable.

Food for thought in this piece by @saraimari.bsky.social on how AI will affect science. Warning: contains philosophy! www.noemamag.com/the-death-of...

In a universe where everything exists, nothing is possible

In a universe where everything exists, nothing is possible

We have no idea what alien intelligences are like (or if they even exist at all). What little we know about what is “alien” or “intelligent” is put in stark relief if AI is truly the most exotic ‘intelligences’ we can imagine, when these are a mirror of the human niche

"creativity" emerges in wake of deep distress felt when one's experience of reality is not our consensus - what remains is no other choice but to disrupt the consensus

"The death of the scientist is the loss of the inner world that creates an idea, but this is also when the idea can become shared, and the inner world of the societal system of debate and controversy comes alive" www.noemamag.com/the-death-of...

“If we misunderstand what science is, mistaking automation of method for the human project of collectively constructing, debating & refining the symbolic representations through which we make sense of reality, AI may foretell the death of science.” — @saraimari.bsky.social #science #ai

Language remains the most profound technology we humans ever developed because its implication is that our mind is shared

Last week's dialogue with @saraimari.bsky.social is online.

On ontological anarchy in assembly theory … really enjoyed the deconstruction of both reductionism and emergence in this piece by Michael Ardoline. I will happily take ontological anarchy over reductionism or emergence any day www.pdcnet.org/pdc/bvdb.nsf...

This year's issue includes: - Essays from @blaiseaguera.bsky.social, @kalladomcdowell.bsky.social, Benjamin Bratton, and @saraimari.bsky.social consider how to define and differentiate intelligence, computation, and identity in the face of synthetic minds.

"Information and the Emergence of Complexity" I'm looking forward to an IAIS dialogue with @saraimari.bsky.social, moderated by Gordana Dodig-Crnkovic. Wednesday, November 19th, 2025 17:30 (CET) | 11:30 AM (EST) meet.google.com/gqm-frcd-apg... More info: sites.google.com/view/iais-in...

As a species we see reality through mental models, the deepest rooted is the socially constructed one we feel like we live inside which we call our own “mind”. Seeing ourselves outside of the models we currently live inside will be one of the greatest challenges for science in the coming centuries

If you are too confident in your representational maps of reality you will miss seeing reality

What we communicate are models of the world, not the world.

The platonic world does not exist “out there”, it’s a projection inside your mind when you must construct internal representations that are devoid of the history and causal contingency in the objects of your experience

Mathematics without ontological commitment is not a theory of reality, it’s an interpretation, which is how we landed on the current landscape of descriptions in quantum mechanics, none of which are satisfactory

Contrary to science fiction an infinite number of copies of you do not exist, you only exist here and now, and the closest things to copies of you are the other humans inhabiting this same rock at this same time.

Asking about alien lineages of life requires deconstructing four billion years of evolution and attempting to look into a space of possibilities we’ve never seen in our entire history

“You only exist here. And you exist here because four billion years was necessary to construct you on this planet.” - @saraimari.bsky.social

It is an odd feature of the human mind that we use all these things that don’t exist to reason about the ones that do.

Recursive Worlds (@saraimari.bsky.social): Life reshapes how we think about reality: best understood in time, not space. Earth is a self-constructing system: ‘a very deep stack of recursive objects’ built over 4 billion years. recursiveworlds.antikythera.org

Unfold the history of proteins and you find rich, unexplained complexity. This August, an SFI working group with @ELSI_origins and @ASU_SCAS used machine learning and assembly theory to explore hidden rules underlying all folded matter, from proteins to potential new drugs. santafe.edu/news

We should always take seriously where computational descriptions fail, as it tells us something about where the current boundaries of what we can describe in language lie

Of all the materials that compose you, the most significant is time. It takes billions of years for our universe to generate structures like us.

Known examples of life persist across scales from the molecular to the planetary. Death also is a matter of scale, raising the question of which of our deaths matters most? The individual? The lineage? The biosphere/planetary? Or the universe?

Myths are very much alive in modern societies, and apart from in few cultural practices, like science, we have just as hard of a time recognizing when we are steeped in them as our ancestors did.

Toward Planetary Maturity: The RAND Corporation's new proposal for astrographic standardization will help to provide a standard grammar for #PlanetarySapience, thus helping to "mature the technosphere," as per @saraimari.bsky.social. My latest substack: nilsgilman.substack.com/p/toward-pla...

Finally, in the second Seeds of Story post, @saraimari.bsky.social's Life as No One Knows It offers cool new physics and a metric for whether that thing out there is aliens: reactormag.com/the-wild-ali...

Life as No One Knows It, my conversation with Sophia Al Maria during the inaugural AIR festival (also named Life As No One Knows It!!) now on Aspen Public radio, an incredible week celebrating art, artists, creativity and ideas with so many amazing humans ❤️ www.aspenpublicradio.org/ideas-speake...

“Human” is the most amazing configuration of matter any of us has ever observed, yet we deeply under appreciate what we are

What is the human aesthetic choice behind Google's algorithm ‘People also ask' - it seems like it prioritizes content scaling over relevance and/or depth. The answers are depressing and boring. Would love it to add value to my original search.Why is understanding NOT the aesthetic we are going for?

Physics for a new century should solve what we, and all life, share fundamentally youtube.com/watch?v=43Re...

@r-emrys.bsky.social explores the work of physicist and astrobiologist Sara Imari Walker, and how her insights into Assembly Theory and the origins of life might influence the future of science and science fiction 🌱 reactormag.com/the-wild-ali...

Many cannot see past the current representational maps that architect our minds & want them to remain static, but it’s important to recognize these can always be revised - the models we inhabit in our own minds should always be changing if we are to really come to understand anything about our world

The most transformative theories never come from trying to build better mathematical representations of current theories. Instead we get them by making direct contact with observations not accounted for in our existing map of the world.

What is Life? In her Long Now Talk, astrobiologist and theoretical physicist Sara Imari Walker (@saraimari.bsky.social) explores the fundamental nature of life and how can physics help shape our understanding of how it arises in the universe. Full talk here: youtu.be/zhzxQraB2m0?...

"We are lineages, not individuals." @saraimari.bsky.social is such a badass! Making great & under-appreciated points in this @noemamag.com piece: www.noemamag.com/ai-is-life/

the term “prebiotic” in origin of life research is ironic given that it almost always refers to chemistry post-selected to be of interest to biology on Earth

The origin of life is not computable, yet it happens anyways

Math is evolved

Math is physical

Science is not about an automaton-like process of observation, measurement, experiment. It is about building explanations improving on those of our ancestors, ones we might want to gift our descendants if they choose to accept them.

Automating an experiment is possible, automating science is not - there is no scientific “super-intelligence” to train on the methods of science given no one can agree exactly what science is. It’s modern myth making to assume otherwise.
