All true, but I think its a valuable exercise to try to design/understand/exploit these dynamics

I think the question and article is fascinating. I do think that one should not only look at the genetic representation, and the algorithm a cell runs, but also the formalized environment that runs the simulation.

I’ve been thinking about this for a few years and I truly believe these cells need to be able to “move” in either a 3d lattice similar to a cellular automata or become nodes in some cyclic graph (or maybe both).

For the genetic representation, I had an insight that DNA/RNA looks strangely similar to SKI calculus (combinators) and have been using a Church encoding to translate the SKI program to an “action” per turn (move, connect, spike, divide, etc.). It has a nice property that the cell’s “program” and the spikes between them, and the input/output to the simulation itself can be the same thing (just a string of combinators).

Either way the author is spot on when it comes to this sort of thing having the properties 1) “always on” (no separate training mode), 2) local interactions, 3) everything stems from a genome, 4) each cell is its own little mini-program with the same genetics as everyone else.

All I can say is that evolutionary program is hard and takes either massive compute or large timescales to run the simulations. Fascinating stuff though

The abstract implies that strictly local updates are a hinderance to high res, however i would have thought there would be an interesting way to get speed up gains from neighbor-only traffic on GPUs CAM-style. am i making that up?

Nice, this definitely needs to be standardized
Charmbracelet is amazing. Will there be an equivalent of Claude Code's CLAUDE.md files?

Insulin is lethal at higher dosages, so there is definitely an argument. My counter would be that someone who has to self administer this drug 5+ times a day should have the right to make determinations about dosing
Re:Ask HN: What are you working on? (April 2025) on Monday April 28, 2025 @11:59AM (#43822930)
Technically there is unsanctioned access (someone reverse engineered the real-time APIs [1] which I ported to Go). I think the FDA does not want easy access to real-time values so that folks can't easily recommend insulin dosing without oversight. I am personally of the opinion that it is our right to have programmatic access to the real-time data and do with it what we please.

Would love to get in touch to hear more about your long-term vision for the project!

Also recently diagnosed and just open sourced how I'm using AI to count carbs + get insulin doses [1]. Biggest issues I've seen to starting a legit business is not having sanctioned access to real-time blood sugar values (the APIs are all one hour behind), and dealing with the FDA. Love the idea of more tech-enabled diabetes management, good luck!

Recently diagnosed with Type 1 Diabetes, and learnt quickly that calculating insulin doses sucks (and you have to do it 4+ times a day). BolusGPT is a ChatGPT plugin that translates meal descriptions into nutrition information that is fed into an insulin dosing algorithm. Also hooks up to Dexcom CGMs. Happy to answer any questions!

I've always thought that gravity exists because without it, matter doesn't get close enough for interesting things to happen.

I've wondered for a while if Artificial Life is in its own winter, waiting for someone to apply the lessons of scale we learned from neural nets.

Is it only academia and Google Research that is funding these kind of artificial life passion papers? Wondering if anyone knows of real-world applications / companies working on them.

Re:Darwin Machines on Tuesday July 16, 2024 @10:45PM (#40982128)
I’ve been noodling on how to combine neural networks with evolution for a while. I’ve always thought that to do this, you need some sort of evolvable genetic/functional units, and have had trouble fitting traditional artificial neurons w backprop into that picture.

My current rabbit hole is using Combinatory Logic as the genetic material, and have been trying to evolve combinators, etc (there is some active research in this area).

Only slightly related to the author’s idea, its cool that others are interested in this space as well.
