Nested agency and grammar-based language models (39/n). • Formally titled as “Nested pushdown automata and context free grammars (1/n”). Renaming to better reflect the design project’s origins as an exploration into physical computation.
Nested pushdown automata and context free grammars (1/n). I am one of those people that needs to build something before I feel I understand how it works. In an effort to take a deeper dive into the Theory of Computation I’ve put together a nested stack machine in a FPGA. At this

(1/2) A few thoughts on Blaise Agüera y Arcas (*). • BrainFuck (BF) might be an awkward name for a minimal programming language, but with only eight commands, its choice brings the paper’s numerical explorations within possibility. (Noting, BFF having 10 commands.) • But the

Numerous recent replies have mentioned Blaise Agüera y Arcas. Taking this as a hint I’ve watched two YouTube videos and am currently reading through his BFF paper. • Somehow, I’ve managed independently to arrive at similar conclusions to his. We certainly share common ground

While Nick Lane has fully convinced me that deep-undersea vents had to be where life first began. Such vents still don’t explain the appearance of the first self-replicating molecules like RNA. • Von Neumann approached the problem of self-replication with his notion of a

Imagine arriving at your hotel for a night's stayover, you're by yourself, no other humans around, and you see it staffed everywhere by "robust" humanoid robots. • Talk about "uncanny valley" level of creepiness. There is a reason for the "harmless looking toddler bot" look; its

Both chaotic dynamical systems, as well as systems driven far outside of equilibrium, are capable of spontaneous order generation. • But none of such resultant orderings, are capable of instantiating physical computation. • Thus, taking physical computation as fundamental for

Consider the simple board game of checkers; two players, red and black. • This can be modeled as a nondeterministic finite state machine. The transition function involves single piece manipulations. There is a single start state, with multiple possible halting states
@CAS_ReproLab Why can't it be "all of the above?" Which is exactly how nested computation (agency) works; multiple, simultaneous computational processes, all sharing the same physical hardware, with one layer channeling the other layer's "subroutine-calls". @Laing_BrentonT @CAS_ReproLab

No doubt, the most obvious industrial entry point for humanoid robots are the hotel-motel service occupations. • And until you start seeing commercial movement into this labor market, everything else being said about humanoid robots is just sales hype. • As an example, no hotel

Just finished reading “What Is Life? Revisited” by Daniel J. Nicholson. Link in the replies. • Time well spent. Left me with some useful insights about Schrödinger. Fresh things to think about. But what absolutely floored me was the single observation shared below. Necessary

When an LLM can independently figure out how do this, then it will be time to get worried.

The first 20 seconds of this video is exactly what I see when I imagine an IC processing data and program at the silicon level. • A geometrically very complicated 3D abacus with packets of charge acting as the beads. • And this is the image I'm trying to convey when I talk
What open source ASIC tools am I excited by in 2025? OpenEMS, 3D viewers, Surfer, OpenROAD, and lots more! Check this article for all the links: https://t.co/zC3soBjMPw

There is no physical theory of choice. • If an algorithm is a sequence of choices defined by a set of rules, then how exactly does a physical system instantiate an algorithm? • Without any understanding of how Mother Nature does this, …expecting the formal Theory of

This is great! 'The irony that a physicist may have been largely responsible for a generation of biologists ignoring the stochasticity in the systems they study'😅 So many influential ideas are more often cited than read. Looking at you 'Warburg effect'🤨
I had SO much fun talking to Paul for almost 2 hours about my new book on Schrödinger & molecular biology. Easily one of the most enjoyable podcasts I've ever done. Check it out! P.S. CUP has made the PDF of my book free to download for two more weeks. Link is in my pinned post

The short, but no doubt, unsatisfactory answer is no. • Physicalism allows something non-material to still qualify as physical; information being an archetypal example. Note, this drops Materialism out as a philosophical contender. • Put simply, if something is governed by the

Conflating “a description” with “a definition” is another error in presentation that frustrates debates ranging from "What is intelligence?" to "What is consciousness?" • A description represents a black box view, while a definition represents the white box view. • A

Any comprehensive answer has to start with the recognition that physical-computation and agency are synonyms. • And that the proverbial observers in quantum mechanics, Alice and Bob, are themselves archetypical examples of agency. • Attempting to apply Gödel and Turing to

Formal mathematical constructions can be used to model our universe’s physical laws, but they are not the well-spring for those physical laws. • One cannot simply assume the formal results of Gödel and Turing automatically apply to physical computational systems; …one is also
