| archels | Mindell says. “I’m not arguing this from first principles. There are 40 years’ worth of examples.” | 01:42 |
| archels | where's the logic in that? | 01:42 |

| archels | as far as I understand it, his argument is "we could not in the past 40 years, hence we should not" | 02:21 |
| archels | it's a total non sequitur | 02:21 |

| kanzure | "According to documents filed with the Securities and Exchange Commission on April 27, she’d raised $250,000 for BioViva" | 06:30 |
| kanzure | dunno if this counts as diy | 06:30 |
| kanzure | using a CRO definitely doesn't count as diy | 06:31 |
| kanzure | "One current collaborator on the BioViva project is Jason Williams, a radiologist who has attracted scrutiny for offering unlicensed stem-cell treatments to patients suffering from amyotrophic lateral sclerosis, or ALS. Williams says he ceased providing those treatments in the United States in 2013, after the FDA asked him to stop, saying they required agency approval. Williams later established a clinic in Bogotá, Colombia." | 06:32 |
| kanzure | "In an interview, Williams said he was a co-owner of BioViva and had assigned rights in a patent to the company. He said the treatment had occurred in Colombia, although not at his clinic." | 06:33 |

| poppingtonic | to point at a William Gibson novel, the DIY gene therapy story is very close to what happened in Virtual Light | 06:53 |
| kanzure | what, blatant lies and journalism stinking up the place again? | 06:54 |
| kanzure | i'm supposed to be okay with the lie about "DIY" because otherwse it's supposed to make me sound like i'm calling the other stuff a lie, but i'm not falling for this trap. i hate people. | 06:55 |
| poppingtonic | the journalism on this is pretty bad, actually. | 06:56 |
| archels | Kevin Warwick coming to my university November | 06:57 |
| poppingtonic | I see what you mean about the DIY lie. Now anything with DIY bio in the name will look like what this article depicts. | 06:57 |
| kanzure | nah, that has been happening to diybio for a while now | 06:57 |
| kanzure | cathal garvey even took to calling his venture capital program an example of diybio. except it's just companies, startups, and VC money. so..... yeah.. | 06:58 |
| kanzure | maybe diybio should switch to using a name like "biologists going their own way" so that everyone will stay away from hijacking the name | 06:59 |
| kanzure | (in the context of "BGTOW" i would say having a CRO make your drug for you, and then having some random doctor inject you (wtf?), would qualify; it's just certainly not do-it-yourself) | 07:01 |

| archels | yes but I also didn't DIY build my soldering iron or my oscilloscope | 07:55 |
| archels | but they're so commodity it doesn't matter | 07:55 |
| archels | same for DIYbio? | 07:55 |
| kanzure | er, i don't know, what am i supposed to be judging? | 07:56 |
| archels | well, I think this is more than a discussion about semantics | 07:56 |
| archels | the semantics of the term DIYbio | 07:56 |
| archels | it's about not being able to do every single step of a constructive/creative process absolutely single-handedly | 07:57 |
| kanzure | the utility of the term is zero if it means "business as usual" | 07:57 |
| kanzure | to their credit, they did not claim it was diy-related, rather that was the journalist's fault | 07:58 |

| kuudes | at least over here in finland, head circumference of newborns has been steadily increasing, and they had again recently to enlarge the head circumference norms | 08:20 |
| kuudes | for some reason they made a note that "larger heads do not mean more intelligence" even though the article portrayed both head size and intelligence in a positive light, I wonder why it still seems worth mentioning to someone? | 08:20 |

| kanzure | okay done with the call. have transcript, but summary is supportive but otherwise done dealing with synthesis. | 14:10 |

| archels | berndj: "everything everywhere is always exponential" or something like that | 14:13 |
| berndj | archels: including the difficulty of achieving each increment in intelligence | 14:14 |
| archels | nah that part is elided | 14:14 |

| kanzure | berndj: you can have high cognitive ability and still not get a singularity anyway. | 14:15 |
| berndj | kanzure, the whole "singularity is upon us!" thing reminds me of zeno's paradox, where it only seems like a singularity because of a poor choice of coordinate system | 14:16 |
| berndj | i'd *like* to be worried about something as geeky as an AI armageddon, but... i'm not | 14:18 |
| kanzure | well, you're not wrong | 14:20 |
| kanzure | not sure what you want us to do about this though :-) | 14:20 |
| berndj | convince me that i should be worried? | 14:20 |
| kanzure | wrong channel for that | 14:20 |
| kanzure | you're thinking of #lesswrong | 14:21 |
| berndj | oh :-/ | 14:21 |
| kanzure | we aren't the existential worry warriors in here | 14:21 |
| kanzure | (XRWs just doesn't have the same ring as the other *W, but whatever) | 14:22 |
| berndj | maybe i misunderstood this channel's purpose/interests/otherthings | 14:22 |
| kanzure | berndj: there's a good overview here, http://diyhpl.us/wiki/hplusroadmap | 14:22 |
| berndj | i read too much into "transhumanism", i think | 14:23 |
| kanzure | fenn: the conversation was a little strange.... like, he listed out things to worry about when engineering such a machine, such as humidity, but he treated this like an insurmountable set of problems (probably just exhaustion about having to find all of the problems? or that he doesn't think anyone is careful enough to check all the parameters and conditions..?) | 14:24 |
| kanzure | berndj: well, i mean, yes many transhumanists are interested in worrying about singularities. but i find the utility of this worrying to be very low. | 14:24 |
| kanzure | worrying about a singularity isn't going to build me a dyson sphere, or reveal the location of the stolen data plans | 14:24 |

| kanzure | too late | 14:41 |
| kanzure | fenn: yeah i think there's a large anti-engineering bias in general in this field. i don't know where it originates from. | 14:42 |
| kanzure | i mean, they aren't explicitly anti-engineering... they parrot the benefits of machines and tools and specifications... but then it never materializes. | 14:42 |
| nmz787_i | well seems like he answered that anyway with "We're out of the oligo synthesis thing." | 14:42 |
| kanzure | or if it does materialize, it's only at much larger companies. | 14:42 |
| nmz787_i | aka 'we gave up' or 'that is too boring for us' | 14:42 |
| kanzure | well, i think it's because in 2014 he moved out of george church's lab | 14:43 |
| nmz787_i | I wonder who is doing the reviews for actual synthesis experiments/research... | 14:46 |
| nmz787_i | if no one is... well I guess that means better chance for one of us to get there first | 14:47 |

| yoleaux | "James M. "Jim" Williams (April 14, 1948 – June 12, 2011) was an analog circuit designer and technical author who worked for the Massachusetts Institute of Technology (1968–1979), Philbrick, National Semiconductor (1979–1982) and Linear Technology Corporation (LTC) (1982–2011). He suffered a stroke on June 10 and died on June 12, 2011." — https://en.wikipedia.org/wiki/Jim_Williams_(analog_designer) | 14:49 |

| nmz787_i | "Acoustic thermometry is an arcane, elegant temperature measurement technique. It utilizes sound’s temperature dependent transit time in a medium to measure temperature. The medium may be a solid, liquid or gas. Acoustic thermometers function in environments that conventional sensors cannot tolerate. Examples include extreme temperatures, applications where the sensor would be subjected to destructive physical abuse and nuclear reactors. Gas | 14:51 |
| nmz787_i | path acoustic thermometers respond very quickly to temperature changes because they have essentially no thermal mass or lag." | 14:51 |

| poppingtonic | how much do you think it would cost to make only one of those? If you were machining all the parts yourself, testing and doing QA? | 18:47 |
| kanzure | well how many are they making? | 18:48 |
| streety | it's priced at $200 for each keyboard so they're looking to make a thousand | 18:49 |
| poppingtonic | No, that would mean they break even. | 18:50 |
| kanzure | no way they are doing it at-cost | 18:50 |
| streety | I'm not suggesting that is how much it costs to make, only that the price they are charging is $200 | 18:51 |
| -!- c0rw|awa_ is now known as c0rw1n | 18:51 | |
| poppingtonic | The number has to be so that they make a profit. Which means that it would be cheaper than $200 to make. | 18:51 |
| streety | yes | 18:51 |
| poppingtonic | Wait, not "has to". It just seems like that to my mental model which includes economies-of-scale calculations in hardware projects. | 18:52 |
| streety | are you talking about the unit cost for them or the cost of DIYing a equivalent device? | 18:53 |
| poppingtonic | Both. To my mind, DIYing an equivalent device would be more expensive than mass-producing, whatever "mass" means in this context. Unit cost is cheaper and subject to deals with manufacturers etc. | 18:56 |
| poppingtonic | Unless all the per-unit expensive-to-manufacture components are designed and sold en-masse, separately, in such a modular fashion, and so cheaply that it's just a matter of designing a form factor that looks exactly like that one device. That seems unlikely. | 18:59 |
| fenn | it's not much different from a kinesis freestyle | 19:00 |
| kanzure | why aren't we past split keyboards yet | 19:00 |
| fenn | because everything is terrible | 19:01 |
| poppingtonic | what, no BCI? | 19:01 |
| kanzure | bci is also terrible | 19:02 |
| streety | yes, the fixed costs would make a single unit expensive, even 10, 50, or 100 maybe. But given that all the design work has already been done, 500 units seems like just as good a run size as 1000 | 19:02 |
| kanzure | marblestone thesis was about possibly better neural interfaces http://dash.harvard.edu/bitstream/handle/1/12274513/Marblestone_gsas.harvard_0084L_11381.pdf?sequence=1 | 19:03 |
| poppingtonic | If I were to simulate what would look like a good growth model for these guys, then if they're looking to get 1000 keyboards out, that means that they're looking for the canonical "1000 fans" who help them get enough word-of-mouth for preorders, more sales and so on. | 19:05 |

| poppingtonic | I actually enjoy reading science phd theses. | 19:10 |
| kanzure | " To address this challenge, we mobilized the intellectual e୭forts of more than 17 collaborators across many disciplines and institutions, asking what it would take to record from all neurons in a mouse brain at millisecond resolution, based on an analysis from ୮ୢrst principles ofphysics and from the known biophysics of the brai[434]. This analysis has been featured in a number of subsequent white-papers [144, 585, 136] and was ... | 19:17 |
| kanzure | ... highlighted in Nature Physics[86]." | 19:17 |
| kanzure | "We structured the analysis around three problems: (1) All neurons must be probed at a sufficient rate, (2) the energy transmitted into the brain must not cause thermal damage and (3) the volume of instrumentation introduced into the brain must not cause physical damage. We found that all existing approaches require orders of magnitude improvement in key parameters in order to scale to whole brain observations. Electrical recording is ... | 19:18 |
| kanzure | ... limited by the low multiplexing capacity of electrodes and their lack of intrinsic spatial resolution, optical methods are constrained by the scattering of visible light in brain tissue, magnetic resonance is hindered by the di୭fusion and relaxation timescales of water protons, and the implementation of molecular recording is complicated by the stochastic kinetics of enzymes." | 19:18 |
| kanzure | "We also studied the physics of powering and communicating with microscale devices embedded in brain tissue and found that, while radio-frequency electromagnetic data transmission suffers from a severe power–bandwidth tradeo୭f, communication via infrared light or ultrasound may allow high data rates due to the possibility of spatial multiplexing. The use of embedded local recording and wireless data transmission would only be viable, ... | 19:18 |
| kanzure | ... however, given major improvements to the power efficiency of microelectronic devices." | 19:18 |
| kanzure | "The purpose of exploring the physical limits of brain activity mapping is to identify asumptions whose strategic, purposeful violation could create opportunitiॶ for novel solutions. With Brad Zamft, Michel Maharbiz and Konrad Kording, we have organized a series of meetings among researchers from several fields, in order to architect solutions to the problem of scalable neural recording. This has led to several theoretical proposals ... | 19:20 |
| kanzure | ... which are now being actively vetted at a preliminary design stage. One of these, sensor multiplexing via fiber-optic re୯୳ectometry, is brie୯୳y described in a supplemental note to Chapter 3." | 19:21 |
| kanzure | "molecular ticker tape" is dna polymerase misincorporation influenced by neuron cation concentration | 19:22 |
| kanzure | "In work led by Josh Glaser 227, we also published the first theoretical paper on the molecular recording device concept. This paper establishes limits on the temporal resolution of recording that arise from molecular stochasticity, and derives the need for molecular clocking mechanisms to achieve singlespike resolution. A brief summary of this theoretical analysis is included in Chapter 3." | 19:22 |
| kanzure | i like his approach ("identify asumptions whose strategic, purposeful violation could create opportunitiॶ for novel solutions") | 19:27 |
