Life in life

This is an excellent link, well known in the "community" around this. To add to it, here's a famous and really clear sub-2 minutes representation of the scales involved if it helps make things clearer, for those who've never seen the scales involved: ▶ this video (and that's "just" the Game of Life in the Game of Life). I think I would enjoy helping push the state of the art in this field, but it's far beyond my abilities for the moment. If it wasn't, I would love to work on a new library specifically built for the kind of things like your idea, with the API aimed at working with metapixels-based "hardware", but with the lowest-level constructs (maybe by far) being thinks like RAM or CPU caches as building blocks - while still being able to zoom to the lowest level of cells in the renderer. But it's basically R&D and HPC combined if one wants to offer an interesting alternative to the established libraries. From what I know of upcoming hardware, such a library may have to wait a couple of years and basically target (as in, full buy-in, maybe at the programming language-level, certainly in tooling) the next Apple Silicon-like (or beyond) breakthough in commonly accessible hardware for a nice, "free" performance boost. Maybe GPUs are next?

I remember seeing that video 3 years ago and being blown away. In case someone doesn't already know it, here is Conway's Game of Life simulated in Conway's Game of Life: ▶ this video

It might be argued that one of the dynamic programming (caching) ones would be the best by a reasonable standard. These can be used to simulate absolutely monstrous grids, and is where we see simulated CPUs and whatnot. Here's the game of life running in the game of life: ▶ this video - that one uses Golly.

This is amazing! I've seen "life in life" as a video from ages ago[0], but this is just suck a slick implementation of it! [0] ▶ this video

2017 post has a much-needed youtube video of the metapixels as the top comment: ▶ this video I haven't been able to find one for tetris tho

Here's a nice video showing OTCA metapixels in action, implementing Game of Life in Game of Life. ▶ this video It would be amazing to see this Tetris computer rendered into a video like this.

> This combined with the fact those interactions have been happening for billions of years in parallel at such a massive scale does not make it surprising that persistent and self replicating patterns emerge. On a large enough scale, even improbable events become likely. I don't think anyone has proven the scales necessary for life to happen by chance. What you have done is worked off the base assumption that abiogenesis happened accidentally and therefore the time and scale needed to do so is the age and scale of the observable universe. Under the infinite monkeys theorem that the works of Shakespeare would eventually be produced, but we are not working with infinite time and resources here. We are working "just" 9 billion years and "just" 100 billion galaxies, which, for abiogenesis seems pretty short especially considering what % of planets have zero chance for life due to their composition and star proximity. How many billions of years of compute time across how many parallel computers do you think it would take Conway's game of life with random RNG seeds to simulate itself ( ▶ this video )? Regardless of your answer, I still find it more likely Conway's game of life simulating itself points to an intelligent force of some sort having iteratively created it.

Computers implemented in other computers. Specifically: Minecraft running in Minecraft link or Game of Life running in Game of Life ▶ this video Bonus: Digital clock implemented in Game of Life link Surreal because it makes it apparent that our universe could really be emergent behavior from a simple set of rules.

FWIW: ▶ this video If you allowed toggling particular points manually as input from a controller... probably not too far away from possible!

I think the author is misunderstanding the XKCD comic about rocks [1] (or maybe I am). Just because it's possible to run a simulation of the universe on rocks, doesn't mean that rocks are conscious or turing complete. You can't forget about the person who is manipulating the rocks. The system as a whole is turing complete. Likewise with the bar of iron example that the author gave, you can't forget about the person interpreting the atoms in the bar of iron. The system as a whole is turing complete (and also naturally conscious, because the person doing the interpretation is conscious). And there is nothing physical necessary to represent such systems. You can simulate turing complete systems inside turing complete systems [2]. So I don't see why consciousness has to be a "physical phenomenon" as the author claims. [1]: link [2]: ▶ this video

One thing it doesn't mention is Conway's Game of Life itself. So of course, you can implement Game of Life within Game of Life: ▶ this video

I missed that, thanks! I'll have to take another look. When I think of neural networks that evolve changes in their topology and the weights between those connections, over and over towards optimizing a solution to function, I get the vision of the recursive Life in Life video[1] where Conway's Game of Life is emulated in Game of Life.
