02:39 < maaku> "a self-replicating robot is easily possible"
02:39 < maaku> this is very hard to take seriously
02:40 < maaku> the entire human race with all its combined inguinity is still not able to make a self-replicating robot

04:07 < hprmbridge> kanzure> angiorganoids and vascularized organoids, review article https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9513648/?report=classic
04:09 < TMA> maaku: _making_ is easy (see under the rubric of breeding and/or husbandry) but _engineering_ it is quite a different task
04:10 < TMA> maaku: sorry to nitpick, but I was thinking of what would an autonomous robot entail in terms of assembly just yesterday and it popped into my mind back then
04:10 < hprmbridge> kanzure> you could use biological self-replicating probes https://pubmed.ncbi.nlm.nih.gov/36475966/
05:37 < docl> we also have an industrial ecosystem that is capable of self replication, with humans as a vitamin until we fully automate it (which isn't really AGI)
05:38 < kanzure> do you mean we don't?
05:38 < kanzure> we have so far not replicated our industrial ecosystem so i'm not sure we have that functionality.
05:39 < docl> no, I mean we do. every part and machine is something that can be remade.
05:43 < docl> it's been made and remade countless times. I mean, the machines themselves have pretty much all broken and been replaced. you might find an antique lathe or loom still in use here or there, but the load bearing stuff is newer

06:13 < kanzure> "human touch sensitivity to single atom substitutions in materials" https://pubmed.ncbi.nlm.nih.gov/33929468/ ".. Dhong’s previous work had study participants touch single-molecule-thick layers of silanes – compounds containing only silicon and hydrogen – and it turned out that they could differentiate them based on slight changes in friction caused by chemical differences, including the ...
06:13 < kanzure> ...substitution of one atom within each silane molecule with an amine. But his new study demonstrates that our sense of touch can also identify chemical changes as small as swapping a nitrogen atom for a carbon atom"

08:18 < nsh> the thing about thresholds and quantisation is that you don't really detect anything other than one
08:18 < nsh> s/don't/can't/
08:18 < nsh> hence "the straw that broke the donkey's back"
08:28 < hprmbridge> nmz787> Hence "We further discover that the probability of reporting a single photon is modulated by the presence of an earlier photon,"
08:29 < hprmbridge> nmz787> Basically you're saying the eye detector already could have been half charged to activate, not necessarily affecting the gain of the sensor as the assume.
08:29 < kanzure> i thought there was a greg egan story about a stem cell smart drug called "white something" but i can't seem to find it

12:15 < fenn> "white knights" a cross between a neuron and a leukocyte that forms temporary synapses, see https://greg-egan.fandom.com/wiki/Mother_(retrovirus)
12:15 < fenn> from the short story "chaff"
12:19 < kanzure> for some reason i kept typing "white lotus" thinking that was it
12:20 < fenn> well they're warrior cells you see, so, ah, yeah your name is better
12:41 < fenn> the humans you see today are based on fossil reconstructions; this is what they actually looked like: https://old.reddit.com/r/OldSchoolCool/comments/6axa7x/stephan_bibrowsky_18901932_known_as_lionel_the/
