Here’s an interesting article from the Cleveland Clinic on Tetrachromancy in humans. It turns out that there’s a very tiny percentage of women who can percieve finer gradiations in color, so called tertachromats, as opposed to trichromats which is what the vast majority of humans are considered. People who are considered “colorblind” (which is sort of a misnomer really) are bichromats.
Is there such a thing as sanity blindness?

The article is just the usual facts of how solar and wind are not a solution. This has been known for decades by anyone with a basic knowledge of physics and engineering.

Naturally I agree, even though junior to your expertise.
Yet so many credentialed professionals in physics and engineering are at least paying lip service to the opposite.
If they are sincere, this baffles me. If they are going along to get along, I understand, but I consider them cowards.
I have a friend who was, before retirement, a stellar researcher in physics in her field, which was not climate. She defers to “experts” because of course she expected to be believed about research in her own field. She does not read or research anything to question the credibility of climate “experts.” She never sees contrary opinion because she never looks. And this is an otherwise brilliant mind.
Re: NVIDIA Jetson Orin Nano Super Developer Kit
We now live in a Jetson world.
The Jetson Orin Nano is a standalone Linux computer about the size of a hardback book. It’s the start of NVIDIA’s line of AIs for robots. Rosie the Robot, here we come!
It runs a Large Language Model equivalent to ChatGPT 3.0 — which was hot stuff five years ago. With tuning it can get close to ChatGPT 3.5 — hot stuff from two years ago.
If I wished, I could have audio conversations with it in French.

That makes sense and I believe you.
Once upon a time the likes of Einstein, Fermi and Feynman stomped the world of physics, noticing things, asking questions, making trouble.
There were giants in those days.
I was extremely disappointed to learn that my brilliant college friend has no curiosity outside of her field. She is also a knee-jerk leftist in politics. She told me her exposure to news is what she sees on Google News on her way through to science news. Other than astrophysics, her mind is closed.
PhD degreed polymath Eric Weinstein points out the US physics Nobel Laureates average age was in their 50s a half century ago— but today, it’s 70s.
WHAT HAPPENED? He points fingers at the Federal government tracking science into certain areas, and denying funding to others, especially anything defense related.
THIS was the core rub behind Marc Andreessen’s account of a White House visit with Biden science advisors, about one year ago.
And therefore, the Silicon Valley rebellion against the Empire began!
Political authorities were going to exercise control over AI and deny any private rival companies, says Marc.
Weinstein point out the inflection point in the 1970s — and before this point supersymmetry was almost never heard. After that point, it came to totally dominate particle physics.
No, there are really people who are actually colorblind in the exact sense that your first impression of “colorblind” is.
They are also called “colorblind.” (And are legally blind because they lack visual acuity.)
Thanks, Nonapod, for the Cleveland Clinic’s pretty explanation of 4 color sensitivity, and why it’s only in women. Because it’s a mutation on the L long wavelength sensitive cone gene on the X chromosome and only manifests if it’s paired with a normal L gene. And only women have 2 X chromosomes.*
Unmentioned is how such a sensitivity might have developed—like women gatherers being able See which fruit is over or under ripe, so they eat a bit more healthy food. Noted without much discussion was the idea of needing a 4th channel & brain processing to take advantage of the additional sensitivity, which many women with the genes don’t have so they see/ process fewer colors then they see/ sense.
Reminding me of thinking that many men have some magnetism sensitivity, as they think migrating birds have, to better sense direction. And maybe lots of men have sensors for it, but don’t know to process the sensory signals.
Which, as I write, relates to a long ai post about education & learning & how much of Ivy+ reputation is just signal, not learning. And now I wonder if companies are learning to process the signal that an Ivy degree is much more signal than actual learning, tho there is some. Will ai be like a Whispering Earring?

$249. This is an astounding drop in compute costs. And so soon.
