Growing Rat Neurons to Play Video Games [video]
- yoyopa 3y agowhy rat neurons and not people neurons?
- claytonwramsey 3y agoIt's explained in the video. Rat neurons are more than enough for this application and are much cheaper to come by.
- yoyopa 3y agothe video is half an hour long. probably the worst way to convey information
- vba616 3y agoboss: you might try doing X as your next project me: ok boss: actually, we can't do X, we don't have access me: ok boss: you might want to watch this video on X, though, it's interesting me: no

- eurekin 3y agoSo much good information is presented now as videos... I'm thinking of automating that. A service, which follows your watched yt videos feed and automatically saving a transcript. Maybe with some LLM summary and few screenshots - as simple html page. I believe people keep producing videos, since it can be monetised nicely
- mdp2021 3y agoYou should work on an engine that adds punctuation to the subtitles. They are pretty raw as they come - they normally require some post-production to be made into structured text. Probably something already exists? LLMs could be good for heuristically obtaining punctuated text - but since real understanding is required, other systems should be employed - such as a transformers based ANN (speech + raw_transcript → punctuated_text). The issue of "real understanding" is that which should discourage «LLM [generated] summar[ies]» - I have not yet seen any that show actual understanding of the original. "No work" is often better than "bad work".
- eurekin 3y agoI did some initial tests and found that whisper.ai gets transcripts a loot better. Might improve punctuation. Also, when asked to summarize, even Vicuna removed all portions of irrelevant talking (like to the crowd on a meeting) and jokes. Might be worthwile to finish that
- hombre_fatal 3y agoDisagree. I’d rather listen to information while doing something else. Most info isn’t so important that I should stop moving and sit down and read it.
- mdp2021 3y ago> listen to information while doing something else Hard to find intellectual material that does not require full concentration. Even those few pieces that seem to be highly digestible - they typically do not speak to the intellect and/or do not get fully processed anyway, under condition of shared attention.
- taneq 3y agoIt’s iflscience not ifwtsscienceid (want to study science in depth). :P
- mdp2021 3y agoThanks for the recommendation. If you also can peek to videos in your multitasking: there are many related YT channels around, but if you are into leisure time spending on divulgational channels, there is probably little better around than Curiosity Show, the Australian (Adelaide?) TV channel featuring Rob Morrison and Deane Hutton in the '70s and '80 - for the young; Steve Mould, ongoing YT productions, picking stimulating topics of non immediate evidence.
- throwuwu 3y agoThere’s a substantial amount of important visual information in the video. It’s not just stock photos.
- ramraj07 3y agoI’m not sure a more fundamental point is explained or addressed: when forming ad hoc networks like this do we expect anything different at all with human neurons ?
- nzach 3y agoThis is addressed in the video. Cells growing in a flat plane don't form complex connection as we would see in a real organ. One way address that is to grow the as organoids. You can think of organoids like 'cells growing in a non-flat surface'. This mean the cells would have all 3 dimensions to grow and form connections. The problem with that is that you need a LOT o cells, and they are expensive. The way around it is to create neurons from skin cells. But that has its own set of challenges.
- FrustratedMonky 3y agoBut, funny that the reason was they were 'cheaper', not that you can't buy human neurons if you wanted to.
- xkcd-sucks 3y agoIt's a lot easier to work with rat neurons. TL;DR a bit like "why use Postgres when you could be using Oracle?" ... or something, just thought of that because process overhead really does lead to safety and compliance audits Opinion that's years out of date: * The biosafety level is lower (all human tissue is automatically BSL2 or BSL2+ because it might have HIV and stuff) * The best neural cultures (neurons + supporting cells) come from actual tissue, there aren't good stable immortal cell lines for neural cells. So this generally means fetal cells which for human tissue involves a boatload of process and bureaucracy. Fetal rats, *comparatively* have little bureaucracy. * iPSC cells (Induced Pluripotent Stem Cells / "stem cells harvested from adults") can generate neural cells but it's several stages removed, and still more process overhead if it's human tissue * It's better to harvest actual brain tissue than grow them from progenitor lines. You can grab partially or fully differentiated cells by dissecting them out of specific locations (i.e. hippocampal neurons, dopaminergic neurons, ...). Forcing a population of progenitor cells to develop into what you want is a massive pain / still an "unsolved problem" in the sense that you can't buy a grow-a-brain kit. (NOT facetious, most labs that aren't dirt poor use kits as much as possible and it is TOTALLY worth it)
- dehrmann 3y agoDidn't I see someone fake this with dog cells ~15 years ago?
- palad1n 3y agoWell, that's horrifying
- throwuwu 3y agoIt’s a funny one. At first: how horrifying to subject brain cells to the world of Doom! After more info: oh, they don’t perceive the horrific setting nor possess the context to know they are in a simulation. They just have inputs and outputs, comfort and discomfort. That’s not so bad. Upon deep reflection: oh God! We are just a scaled up version of this! Our perception of the world is just a tiny slice of reality filtered through limited senses. For all we know we could be trapped in a simulated hellscape with no chance of ever breaking free!
- oneTbrain23 3y agoLikely we are in simulation with ppi resolution set to planck constant. Matrix isn't so far fetch. Now we have to wait for Neo.
- yazaddaruvala 3y agoMore like, we have to invent Neo FWIW, even if we are all in “prime” and this is not a simulation. There is always the possibility of inventing a way to elevate ourselves out into a higher dimension. Either way, same goal really.
- drdeca 3y ago"a higher dimension"? If you mean to suggest that our reality is like, a (3+1)D slice of something bigger, I don't think we have much reason to suspect that, and, even if it were true... Well, ok, I suppose maybe we could construct some kind of vessels in this larger space which could like, well, if mind-uploading is achievable (or, even if just mind-transfer-to-a-new-medium is possible) then conceivably we could do that to be able to live in such higher-dimensional space? But, unless it granted us more control over our environment in a useful way, I don't see why that would be particularly desirable? Well, I guess it probably would grant some more control, but like, our minds, I think, are suited for the kinds of experiences that humans have generally had, not so much for, whatever constructed bodies we might somehow build for such a higher-dimensional space. I don't mean like, "our minds aren't well-suited to navigating in higher-dimensional spaces, with higher-dimensional sensory-input". That might be true, but maybe we could adapt to that part without too much of an issue, idk. Rather, I mean stuff like, it is important that we have things like, the feelings of sharing a meal with one's loved-ones, hugs, and other physical expressions of affection. (I am not making the claim that hugs are a human cultural universal. I don't know. But I'm fairly confident in my assumption that all successful human cultures have some form of physical expression of affection.) Now, I'm not saying that such things would be inherently impossible with more dimensions of space. Why would they be? But, I'd imagine that even if our minds can adapt relatively easily to piloting a body in a higher-dimensional space, that, probably the combination of our minds and whatever bodies we constructed for navigating such a higher-dimensional space, and the kind of larger-environment that there might be in such higher-dimensional space (I imagine it being fairly desolate, as if there were things living there we would probably be toast already) would not be conducive to having those experiences in those bodies. If you mean more generally, "some true-er view of reality" and not necessarily "higher-dimensional space" (but still in a way that differs substantially from reality-as-we-currently-perceive/experience-it)... Well, sometimes I imagine that heaven might not operate like (3+1)-dimensional space (perhaps not corresponding to any kind of smooth manifold). In this case, I would imagine that this would be fine (by assumption of it being "heaven"), because either we would always have been designed so as to be compatible with it, or it would have been designed to be compatible with us, or both. (side note: If I had to guess, I think my current guess is that heaven does actually, at least sorta-kinda-in-some-sense(not that I have an idea of "in what sense") be spatially 3D, or resemble that in some way. But, I'm not confident either way.) But, if we are working under the assumption that reality doesn't hold those-we-would-regard-as-people as "special" in any way, such that we would have particular reason to expect it to be good to us outside the scope we find ourselves in currently, then, I would generally not expect this this "higher reality" or whatever, to be well-suited for us. Maybe it could be exploited in some way, to make things better in this portion/view of reality, and maybe more parts could be made to be like this one, but, under the assumption of an uncaring universe, I would expect that any "higher/true-er reality" would not be really nice for living in.

- codeulike 3y agoIts like the setup for one of those episodes of Doctor Who that involves lots of running down long corridors
- guptarohit 3y agoOther videos on his channel is also quite interesting
- mcast 3y agoThought Emporium, Nile Red, and Styropyro are YouTubers who are a few degrees away from being dangerous criminals (I say this in the lightest way possible) but channel their talents for educational videos.
- jona-f 3y agoAre you serious or trying to make a joke? I don't get it. Generally nice people, maybe slightly narcissistic, like any youtuber, maybe irresponsible. These people are nowhere near being "dangerous criminals", that's just slander.
- mcast 3y agoI'm not trying to slander them, they are very talented people. They are all people who know how to build dangerous things.
- davrosthedalek 3y agoEvery (experimental) scientist on earth knows how to build dangerous things.
- mcast 3y agoThat's true but I would wager most scientists don't stockpile on explosives and chemicals like cyanide and arscenic at home.
- jona-f 3y agoI really dislike your framing of chemistry enthusiasts as potential criminals. All the prohibition around chemicals makes it real hard to do fun stuff. Especially for people who don't want to break the law. Dangerous criminals don't care and will always find a way.
- dharma1 3y agomaybe Tesla could finally do FSD with a bunch of rats neuralinked to the car
- waste_monk 3y agoCan't wait to pre-order my 2024 Tesla RatKing
- fahadkhan 3y agoImagine not being able to get somewhere because your car has caught a cold.
- BasedAnon 3y agoi hate this, it makes me viscerally angry
- akomtu 3y agoThis was the plot line of Quake: an unholy union of organic lifeforms and machines went rogue.
- Narishma 3y agoI think that's Quake 2. I don't think Quake 1 had any kind of plotline.

- shrubble 3y agoAre gamers going to have expensive RNPUs (rat neuron processing units) plugged in via Thunderbolt in addition to GPUs in the future?
- treprinum 3y agoImagine instead of a coop multiplayer using rat brains as your teammates. That might actually work commercially.

- dunefox 3y ago> bridge the gap between biological and artificial intelligence From the moment I understood the weakness of my flesh, it disgusted me. I craved the strength and certainty of steel. I aspired to the purity of the Blessed Machine. Your kind cling to your flesh, as if it will not decay and fail you. One day the crude biomass that you call the temple will wither, and you will beg my kind to save you. But I am already saved, for the Machine is immortal… ...even in death I serve the Omnissiah.
- FrustratedMonky 3y agoSo, autonomous kill drones? Are we sure military hasn't gone further than a video game?
- FrustratedMonky 3y agoI'm a rat. I've been trained to sit at a desk in front of a monitor and type. They feed me coffee to set my neural weights on positive feedback. Really, does no one see the connection to AI, and how humans are nothing but feedback loops. It's all just scale.

- belter 3y agoThe new version of React took some priority...
- ohwellhere 3y agoWhat is the role of stimulus during the growth phase of organoids? Meaning: is it sufficient to grow an organoid and then connect it to the electrodes and go through the training process, or is there an advantage to growing the organoids _while_ connected to stimuli? Naively, it seems like our brains are growing while receiving input and that could guide the growth process.
