Beep boop - this is a robot. A new show has been posted to TWiT…
What are your thoughts about today’s show? We’d love to hear from you!
This past year I stopped watching & unsubscribed to MKBHD. I was disappointed by his speeding, but I also realized: I don’t need to be advertised to by the big tech companies showing things to YouTubers. I don’t need to see robot vacuum ads (same reason I unfollowed SnazzyLabs).
The Powerbeats Pro 2 look cool except I already have AirPods Pro 2.
Jason Snell said @1:22:
If you had an efficient [LED-only] thing that just emitted light and wasn’t very warm, what would be the point?
He’s talking about the incandescent bulb in his Lava® Lamp. While all of the energy of incandescent bulbs is emitted as light, around half of it is emitted in the infrared spectrum.
What would be the point is an interesting question. Funny you should ask! The question was addressed in a 2019 paper, Melatonin and the Optics of the Human Body. The paper notes that the bulk of our melatonin is produced in our mitochondria, and that melatonin production is facilitated by light in the infrared spectrum. Less IR correlates to lower mitochondria performance: less ATP and more free radicals (ROS). The paper notes that infrared light is abundant outdoors (and especially in the woods), but that our LowE windows and move to “efficient” LED lighting has undermined our mitochondrial health.
Populist scientists are oblivious to this biological principle. NDT famously claimed that “[IR radiation] is completely useless to you.” Says who? Did he follow the science before coming to this conclusion? Did Neil consult the Photobiomodulation Database of curated science (8k+ papers) on the topic? He did not. It’s ironic, because some of the best photobiomodulation researchers come from astrophysics.
Nobody is saying we should go back to the OG Edison bulbs. There is a new bulb:
In this hybrid configuration, #122 are LED chips and #120 are little incandescent chambers. This bulb is plenty efficient to meet our current standard of 45 lumens/watt – even though some of the radiation isn’t in the visible spectrum. In one flavor of this bulb, the LEDs can be turned off entirely – a “night mode”.
We need to be a bit less certain about this tectonic shift in our lighting. Jason needs to re-think this. Less lumens and more heat, please. 
- I actually use ADP on my iCloud account. Enabled it literally the day it came out. So far I haven’t noticed anything different in my day-to-day usage, but it’s been on for so long I don’t know if there would be any.
Enabled it because I could, and now with all the news coming out it seems like a solid idea in hindsight.
Same here. I prefer to keep my data private. I don’t subscribe to the “nothing to hide” argument.
