- https://www.youtube.com/channel/UCLB7AzTwc6VFZrBsO2ucBMg robert miles: "ai safety"-crowd ai safety videos. don't let this be your only perspective on ai safety, the ai safety people are great but their whole community has a shared anxiety disorder. heed their warnings but don't have the meltdowns they accidentally encourage; just imagine yourself petting the ai safety researchers on the head and going "there there, the ais will be friendly because of your work, thanks for getting me up to speed" and listen thoughtfully. emotional tone warning aside, I do like this channel. just not as much as the simons institute's videos on ai bias, alignment, safety, objectives, etc etc etc.

there, some channels. there are a ton of channels already mentioned here; it's great having an index of them, but remember to browse them yourself and skim some videos.
Looking through it, but isn’t this the channel that critiques other channels for the sake of critique? I mean, I don’t think School of Life or any other channel is perfect, but a YouTuber building strawmen and attacking them for views isn’t really my thing.
it means a test that was supposed to check if hbo max's software can send emails correctly was run with their real email authentication somehow. I'm so curious how they managed to send it to so many people!
you're correct that this sort of persistent world modeling is needed for self driving cars, but from what I've heard from friends who work in the industry, both cruise and waymo have it. they're very far from using a plain CNN on their video cameras, they've got depth mapping and such and carefully constructed software making use of the perception data to model how the world will change and react to that. idk if it works well, but they definitely know they need it and are trying.
that said, I've driven a tesla on autopilot, and holy crap is was so incredibly bad. I'm optimistic about self driving cars in general, but not about tesla's. it will frequently lose track of the road lines at night and fail to make turns, suddenly beeping at you that you're in control now, with no warning! I only ever used it like cruise control, but I can't understand how anyone driving a tesla would dare use the tricks that allow bypassing the restrictions that prevent taking your hands off the wheel.
huh that's really interesting about fire's emission spectrum!
regarding 6400k - even assuming the sun's spectrum matched the black body spectrum of its surface temperature, its surface temperature is closer to 5770k. but even taking that into account, its spectrum doesn't quite match 5770k in space - and the atmosphere changes it even further. https://en.wikipedia.org/wiki/File:Solar_spectrum_en.svg
I really don't know how much of that change us humans can perceive, but my thinking is that 5000k is probably closer to the center, at least. it might be more of a saturated color, though, since the spectrum is more pointed vs the very flat but spikey spectrum in that plot.
psa: you can get this thing, which isn't the most precise ever, but lets you see this spectral information about lights for cheap: https://www.amazon.com/EISCO-Premium-Quantitative-Spectrosco... - I got one and WHEW CFLs' band lines are really obvious. Also, I feel kind of tickled that I saw the band gap on LED lights before seeing a description of what it is in the source for the spectrum plots in this article (the source being https://commons.wikimedia.org/wiki/File:White_LED.png ).
I'm a bit miffed it seems so hard to find lights that don't have this problem, though. maybe we can improve it by getting the word out that these cheap little diffraction devices can give you a pretty good approximate reading of the smoothness of the spectrum of a light source. Hmm, I just realized I have yet to take this to home depot...
I'm really curious about those MIT incandescent bulbs. If they worked well and haven't been brought to market, it's possible that contacting the people involved in creating them could have good results in making them happen. Perhaps they could be convinced to prioritize it if a case can be made that it can have a significant positive impact on the world?
