ha this is why it was read

Of course. It's a computer designed to figure out the question of life, the universe and everything to which the answer is 42.

Throw this random question in, does DNA spell out sentience

Could you pull out the specific list of ATCG and make a brain

From a neural networks professor:

https://www.inf.fu-berlin.de/inst/ag-ki/rojas_home/documents...

"However, we should be careful with the metaphors and paradigms commonly introduced when dealing with the nervous system. It seems to be a constant in the history of science that the brain has always been compared to the most complicated contemporary artifact produced by human industry [297]. In ancient times the brain was compared to a pneumatic machine, in the Renaissance to a clockwork, and at the end of the last century to the telephone network. There are some today who consider computers the paradigm par excellence of a nervous system. It is rather paradoxical that when John von Neumann wrote his classical description of future universal computers, he tried to choose terms that would describe computers in terms of brains, not brains in terms of computers."

I have no idea what the submitted MIT article is trying to say. Does the MIT article try to make the point that neural networks can be used for computation given ridiculous amounts of memory? They can, but that still does not explain real intelligence. Otherwise, the article makes the same mistakes as pointed out in the above quote.

I don't see the point of asking this question. Like, sure, all physical systems follow certain rules, so any such process will develop in a way that it look like a computation of an algorithm. Also, evolution itself is constantly optimizing organisms to best adapt to their environment, just like a computation.

So asking if life is a computation seems mostly like a semantic musing. Define "life" and define "computation", then see if they're the same.

This feels like the kind of popsci that's written for people who already agree with the author - there's nothing resembling an argument, or even a definition of "computation." There are nods to Church-Turing, but the leap from "every effectively calculable function is computable" to "life is a computation" is larger than anything you could fit in a book.

there are criticisms of life as classical computation or in a more restricted context, cognition as computation [1] - one of which amounts to this: for any computation, there is a frame of reference in which that computation can be modeled, and if so, that frame of reference itself cannot be modeled by said computation.

Only if you broaden the definition of computation to be so general it includes everything.

The basic parameters of affective neuroscience make it difficult to conflate actions with computations. Because there isn't a content to thought, thoughts aren't about things, brains/CNS/bodies lack any units that could be computed, there's only an arbitrary sleight of hand linking life and computation.

Physical phenomena seem to be algorithmic is an illusion, folks. We only have a model of the physical world. The model itself may be algorithmic.

I think Federico Faggin has a much better (imo, coherent and well-considered) take on this [1].

I like the idea instead that some biological components have deterministic optimizations because they’re closer to a molecular form, like DNA, RNA, some protein machinery, etc. because essentially these are driven by some kind of chemistry and physics. Whereas higher level, emergent biological forms are more stochastic in their function, like organelles, an organism, or populations, etc. In that sense, there’s no computation to life, more that life is constrained by the physics of the world in which it develops.

It’s likely if different life forms on another planet, it will have a different “computation” model because its defined by different physics that it experiences during evolution. Though I suppose there will some similarities depending on some fundamental rules of the universe. Will propagation molecules like RNA or DNA always look like helixes, or will the radiation or physics of another planet create another form of propagation molecule we haven’t yet observed. Might make for an interesting experiment to simulate.

this question reminded me of the poetry of terrence mckenna. "Technology is the real skin of our species. Humanity, correctly seen in the context of the last five hundred years, is an extruder of technological material. We take in matter that has a low degree of organization; we put it through mental filters, and we extrude jewelry, gospels, space shuttles. This is what we do. We are like coral animals embedded in a technological reef of extruded psychic objects. All our tool making implies our belief in an ultimate tool. That tool is the flying saucer, or the soul, exteriorized in three-dimensional space."

If true, will computers have rights?

No, and this is a very philosophically confused post because it weirdly does not really give any definition of computation.

Computation really is a fancy word for calculation. What matters about computation is that its teleological. Computers are physical systems designed towards a particular end. A computer is, physically, no different than any other system. What differentiates it is that it's designed and we're interpreting its behaviour in a particular way.

Unless you're trying to make a grand theological argument in which "life" is taken to be some Hitchhikers Guide-like machination towards some end, it's not a computation. Life doesn't compute anything, the same way a falling pen doesn't compute gravity unless in a metaphorical sense.

The article is a pretty good example honestly of the problems of taking metaphors literally, common in the AI space where the author hails from. A similar case "artificial neurons" which are really metaphorical neurons. You have to be particularly careful when making comparisons between intentionally designed technological artifacts and biological and physical processes.

Articles like this indicate we should lock down the definition of "computation" that meaningfully distinguishes computing machines from other physical phenomena - a computation is a process that maps symbols (or strings of symbols) to other symbols, obeying certain simple rules[1]. A computer is a machine that does computations.

In that sense life is obviously not a computation: it makes some sense to view DNA as symbolic but it is misleading to do the same for the proteins they encode. These proteins are solving physical problems, not expressing symbolic solutions to symbolic problems - a wrench is not a symbolic solution to the problem of a symbolic lug nut. From this POV the analogy of DNA to computer program is just wrong: they are both analogous to blueprints, but not particularly analogous to each other. We should insist that DNA is no more "computational" than the rules that dictate how elements are formed from subatomic particles.

[1] Turing computability, lambda definability, primitive recursion, whatever.

If you believe in Dust Theory then yes life could be a form of computation where consciousness is just a pattern of discrete states.

Douglas Adams had something to say about this, I think

Classic John Von Neumann, inventing both the Von Neumann architecture and non-Von Neumann architectures.

I love thinking about life as computation. Cells are computers, enzymes are functions, ribosomes are compilers, nucleic acids are source code...

Enzymes in particular are a lot like unix pipelines. An enzyme catalyzes its substrate's conversion into its product which is the substrate of another enzyme. When cells ingest glucose, it flows through the glycolysis metabolic pathway until it becomes pyruvate, and may be reduced even further if oxygen is present. An enzymatic pipeline. They just kinda float around within the cell and randomly perform their tasks when their substrates chemically interact with them.

  Cell              - Computer
  Enzyme            - Function / Process / Filter
  Substrate         - Data
  Product           - Data
  Metabolic pathway - Program / Script

I've been playing in my mind with an idea for an esoteric programming language modeled around enzymes. The program defines a set of enzymes which are functions that match on the structure of data, automatically apply themselves to them and produce a modified version of the input which may match against other enzymes. The resulting program metabolizes all inputs by continuously applying matching enzymes to them until the data is reduced to its final form.

Computation is a terminal life form that barely resembles life at all.
