maakukanzure: to be precise, I insinuated that embodiment of humans is more complex than we might intuitively guess04:22
maakubesides the typical arguments -- e.g. if you enjoy dance, sports, martial arts, yoga, playing musical instruments, meditation, etc. then these are all tightly linked to your body and you might want to preserve it04:23
maakuit might also be that some aspects of personality are tied to your normal hormonal levels, which are set by interaction with your gut04:24
maakuand how interchangeable is that between people?04:24

archelsmaaku: interesting thought. I originally reasoned that those peripheral hormonal affairs were pretty low-dimensional--personal, yes, but in such a way that only a few knobs and levers could customise it pretty well to an individual. But perhaps it's higher dimensional than I originally thought.05:55

archelswhat's your field, maaku?05:58

kanzureman he hardcoded all this shit? why06:10
maakui got interested in embodiment when I saw a talk at AGI (by Goertzel i think?) about why embodiment is undervalued. that's where I learned about the complexity of the neural-gut interaction, among other things06:11

archelsmaaku: the problem is that few people know how to operationalise these ideas; to pull them out of the realm of philosophy and the social sciences and put them to work in a robot06:13
maakubut what sold me was the argument that moral development might be very closely tied to embodiment -- the desire to protect the body, leading to protection of extended-self, which includes your in-group, etc.06:13
kanzurewhy would that be important06:13
maakuarchels: right, agreed06:13

maakukanzure: i don't know how to answer that. it would be good if machines acted in our interests, no?06:14
archelswhoops, wrong window06:14
kanzureno, it would not be good if it did that06:14
kanzureit would lead people to falsely believe that the machine is incapable of blowing up the planet06:14
kanzureso it would be better if it didn't lie about thta06:15
maakukanzure: ok well i'm not sure I want to argue against that06:15
kanzureoh wait, i might be using "falsely believe" wrong06:15
maakumy point is more that there is/may be a strong connection between embodiment and things we may think are orthogonal, such as morality06:15

maakuso for example, I think embodiment in a virtual environment might be critical to the "sudo design me a nanofactory" bot, for it to learn how the molecular world works and how to design within it06:17
kanzurealso, i should clarify: when i said that embodiment is overrated, i meant human embodiment, compared to unembodied humans06:17
archelsunembodied human is an oxymoron06:17
kanzurein general i do agree that sensory input and exposure to an environment is a good thing06:17

kanzure(however, i don't think that simulated reality will ever be better than real reality for this purpose, because of the problem of writing simulators)06:18
maakukanzure: you may be able to pull an adult out of their body, but I wonder what kind of sociopath you might end up with if you raised an un-embodied baby-brain to adulthood06:18
archelswriting simulators is considerably simpler than changing the laws of physics, though =)06:19
kanzuremaaku: sociopaths would be perfectly acceptable06:19
maakuhang on there's actually an interesting talk going on. back in 10 min :P06:19
kanzure1-3% of the population are sociopaths06:19
kanzurewait a sec, huh, that's less than the estimated rate of pedophilia06:20
kanzurethey are a minority group hehehe06:20
archelshow would an unembodied human communicate?06:20
kanzurewould it have to?06:20
archelsotherwise, what's the point?06:21
kanzureseeing if it works at all?06:21
kanzure"works" is a very broad term here, but it excludes lots of known failure modes06:22
kanzurei'll stop now06:22
archelshow would you know it works? having some random gamma oscillations going on is not very informative06:22
archelsto have someone talk back and say "I'm feeling a little woozy", now that's something to write home about =)06:22
kanzure,title https://github.com/kanzure/papermonk/issues/106:23
kanzure"gamma oscillations" are these even real06:23
kanzurewhy do people still talk about oscillations?06:23
archelsbecause both single-cell membrane potentials as well as large-scale local field potentials very clearly and reproducibly exhibit oscillations06:24
kanzureright, i am not referring to the one about single cells06:24

maakuback06:48
maakuarchels: what do you think of OpenCog's effort to do virtual robots embodied in a blocks world?06:49
archelswell, it's the right general idea, for sure06:54
archelswhat I don't like is their approach of just slapping together random algorithms and GOFAI on the control side of things06:54
archelsthey don't really have a holistic view on how to build brains06:55
archelsembodiment is crucial, but it's not a magic bullet and/or all there is to this game06:55
maakuwell, agreed on that06:55
maakui think CogPrime is a mostly solid architecture, if you blur your eyes a bit06:56
maakubut the foundational level could use a great deal more consistency06:56
maakue.g. they make a big deal about everything interacting via the atomspace, but in the actual implementation the mind agents are not encoded in the atomspace and therefore opaque, and neither is intermediate state stored there06:57
maakuarchels: also, rule-based PLN for inference is yuck06:58
maakui think the "use GOFAI (PLN) where it works, use deep learning (DeSTIN) where it works, use genetic algorithms (MOSES) where it works" etc. is a decent approach though06:59
maakudo i infer correctly that you take issue with that?06:59
archelsyeah, this approach is too complex for the task at hand07:06
archelsbecause in the end it's going to be humans like you and me who need to hook up these different submodules into something that actually works07:06
-!- strangewarp_ [~strangewa@c-76-25-206-3.hsd1.co.comcast.net] has joined ##hplusroadmap07:06
archelsfor complex networks beginning to approach that of mammalian brains, that becomes an unworkable strategy07:06
maakuwhat about simpler minds, like an idiot savant able to design nanofactories, but forget about social intelligence, natural language, etc.07:07
maaku?07:07
archelsthis is a way too modular view of brains07:08
archelsreal brains don't decompose that nicely into little submodules07:08

-!- strangewarp [~strangewa@c-76-25-206-3.hsd1.co.comcast.net] has quit [Ping timeout: 252 seconds]07:09
maakuright, i find agreement on that. that's part of why I object to having mind agents outside of the system07:10
maakuagent internals are likely to be deeply interconnected with the system, e.g. the logic engine making inferences not just on the output of genetic search, but also based on search paths taken07:12
archelsthat's a horrible inside-the-box way of putting it, but yeah =)07:15
maakuyeah so what I am (occasionally) working on is an implementation of CogPrime with a foundation in probabalistic graphical models instead of generalized hypergraphs (kinda like Sigma, which I just found out about)07:33
maakuand with mind agents implemented directly in the graph, in a datalog-derived homoiconic language07:33
maakuso agent operation and evolution can be more transparent and interconnected07:34

maakuthe idea of a bunch of modular agents existing independently of each other is a weakness of OpenCog imho07:52
maakuit's a reasonable experiment to understand the architecture better, but it won't lead to a superhuman AGI07:53

nmz787_imaaku: I didn't think I was complaining about the proof of work, I thought I was complaining about the function to create new coins, which won't happen after some magic number of coins is reached right? something like 21 million?09:14
nmz787_iso why not create coins based only on how well we can solve protein structure, becuase by the time we know how to solve protein structure, I would presume we'd be compleletely out of a scarcity-economy where things like money seem more important09:15

nmz787_imaaku: you mean there isn't two parts to bitcoin, making coins, and verifying transactions?13:32
maakunmz787_i: what do you mean by making coins?13:32
nmz787_ithey have to be generated, which is what the miners do I thought13:32
maakucoins are minted in bitcoin in a relatively uninsteresting aspect of transaction verification13:32
maakuno, minting of new coins really has nothing to do with mining13:33
kanzurenmz787_i: i would be curious to hear how you think bitcoin works, even speculatively, because maaku is about to tell you how it actually works13:33
kanzureand it would be curious to have a baseline for how reasonably clever people, such as yourself, think bitcoin works, prior to interacting with maaku13:33
kanzure*i would be13:33
maaku-- i will refrain from saying more for a few minutes then13:33
kanzurehehe13:33
kanzuremaaku: gotta have your control group13:33
nmz787_iI thought there were some max # of coins hardcoded somewhere, with a coin generation function that takes more and more time as you approach the max #13:35
nmz787_ithen there is some kind of key sharing shit that can't be rainbow-tabled for transactions13:35
nmz787_ior is too-hard-for-todays-computers to reverse/rainbow-table13:35
nmz787_iI haven't studied it at all though, other than a few rather dumn youtube videos13:36
kanzurewho gets coins?13:36
nmz787_iwhoever ran the generate function13:37
kanzurei've run out of ideas already13:39

maakufor questioning your knowledge of bitcoin i presuem13:41
maakuso here's how it actually works13:41
maakucoins are minted as a result of a special exception to the transaction validation rules13:42
kanzureevery node in the network has a copy of the blockchain, and they are relaying transactions and blocks to each other13:42
kanzurethen they store some blocks based off of some rules13:42
maakuin a bitcoin transaction, the inputs must be >= the outputs, and any difference is the fee13:42
kanzurethey do this because there needs to be a database of transactions that have happened13:42
kanzurethe only way to know whether or not you have the money is to have observed all prior transactions (and thus why the nodes store this data, like the blockchain or just the utxos (unspent outputs))13:43
maakuin every valid block there is single a transaction of a special form that is allowed to have outputs exceed intputs by sum(fees) + subsidy(height)13:43
maakuwhere sum(fees) is the aggregate fees for all txns in the block, and subsidy(height) is a deterministic function of height13:43
maaku(what kanzure is saying is also correct)13:44
maakumining is a totally separate process13:44
maakubasically anyone that has observed the entire historical chain and has the current state of the ledger, and bunch together some unconfirmed transactions and call it a block13:45
nmz787_iok, so wasn't I talking about mining, or at least in regards to that protein thing?13:45
nmz787_inot verification?13:45
kanzurethat protein thing turned out to be something different13:46
kanzurebut if you pretend we were talking about gridcoin then my comments still apply13:46
kanzure(justanotheruser pointed out that foldingcoin is not gridcoin)13:46
nmz787_iwtf is gridcoin13:47
maakuoh i see it is a counterparty think13:47
maaku*thing13:47
maakui thought it was a gridcoin clone as well13:47
kanzurethey should probably say specifically "This is not gridcoin, are ideas are terrible for entirely different reasons"13:48
kanzure*our ideas are13:48
kanzurenmz787_i: gridcoin was a project that had all of the properties that i assumed foldingcoin had13:49
kanzure(and was also based on protein folding)13:49
maakuugh. what a braindead way to implement it13:49
-!- lichen [~lichen@c-50-139-11-6.hsd1.or.comcast.net] has joined ##hplusroadmap13:49
maakuyou can inject signed signatures into the result output before submission13:49
maakuand have people join a team instead13:50
kanzurenmz787_i: so the reason why "query the BOINC central server to verify balances" is a bad idea is because bitcoin is specifically designed for the opposite paradigm13:50
nmz787_ii guess i just assumed you only could generate coins if you successfully folded a protein, and to verify your success would use the blockchain verification stuff13:50
maakuwhy force people to have a username with their address in it?13:50
nmz787_iis BOINC equivalent to PDB?13:50
maakukanzure: it works fine as a centralized distribution mechanism though13:50
maakunmz787_i: BOINC is the software underlying folding@home13:51
maakuwe're exploring the exact same thing for the freicoin initial distribution13:51
nmz787_iwouldn't everyone just have a copy of the PDB?13:51
nmz787_iwouldn't that be the blockchain to begin?13:51
kanzurepdb is maintained by a centralized authority13:51
nmz787_ibut you can wget it13:51
kanzureer....13:51

kanzurewhen your bitcoin node connects to the bitcoin network, you do not receive data signed by a central authority13:52
nmz787_ifor de novo sequences I guess you'd need a protein synthesizer and some enzyme assay that would change color or something if the thing folded right13:53
kanzureinstead, you receive correct data according t the rules of the software, and based on different observed blocks and transactions from the network13:53
kanzure*according to the13:53
kanzureso just downloading a data set is not enough13:53
nmz787_ibut when I connected to bitcoin a year ago, my client downloaded a ton of data from somewhere13:53
kanzureindeed13:53
nmz787_iit wasn't just calculating it all13:53
kanzureit was verifying that data based on some rules13:53
nmz787_iok13:53
nmz787_iso we did that already and happen to have it cached in a central db13:54
nmz787_iI guess you're saying that someone could just copy the PDB file, and emit that as it's 'hey I was successful' message13:54
kanzureso remember, yesterday i mentioned that the purpose or design of bitcoin is such that there's no central authority that maintains the ledger of transactions and balances13:54
nmz787_iand then when the other nodes compared, it would match13:54
nmz787_iwell yeah but we can't all have synchrotrons this year13:54
