Some animals have more cone types than humans, especially various birds, so would probably see a violet sky.
We don't have this because common ancestor for all mammals lost all cones but one, perhaps due to being nocturnal, and a second was re-evolved as mammals became more dominant (after dinosaur extension). A third cone was evolved in primates due to a gene duplication that gave us our green cone
We already have mutations, generally in women, for tetrachromaticism, who usually have male relatives with severe or moderate color blindness, in which the X chromosome encodes a different green cone. So they end up seeing red, strange-green, green, and blue, where strange-green is somewhere closer to red than green.
Only a few on record but they tend to have absolutely insane color matching and color perception. One of note worked in the fashion industry and could match fabrics perfectly even in varying lighting (e.g. working under fluorescent but able to match colors that would stay matched in halogen/stage lighting)
I have that already ;) it actually looks like muddy puke green than green. However, green stop lights look more “white” than green.
Some reds look like brown. I hate reds. I’m not sure about the Pantone-like color matching but I definitely see different colors than most people. To the point where my flight license is restricted.
Not sure if you'll see this but you should check color perception with any female relatives, they're much more likely than average to be tetrachromats!
fringe theory just for a bit of fun: since screen use 3 colors diodes, maybe people with tetrachromacy would be less addicted to screens, making them both more grounded in real life and marginally more successful, leading to them having more children?
I have no idea how to test it. But in my heart I know that screens with RG, GB or RB color models would suck enough that any screen addiction would be cured instantly.
> maybe in 100M years we'll get a 4th cone or rod. Probably from nuclear mutation...
There’s a Greg Egan short story (I think it’s ‘Seventh Sight’) where a bunch of formerly blind kids with cybernetic eyes hack the receptors to respond to wavelengths other than the traditional RGB. So perhaps it wont take millions of years.
vacancy rates are extremely low in most cities. That clearly implies supply and demand and not collusion. In new york units are often empty because they are illegal to rent unless massively expensive repairs are made while under rent control. That's not collusion, that is regulatory failure
I feel like we are long into the twilight of mini blogs and personal sites. Its like people trying to protect automotive jobs, the vas majority were already lost
Silver has plenty of industrial uses. Very little has changed in industry to cause demand or supply shifts to match the massive price swings. Thus a lot of this is probably meme investors gambling
Fun fact about silver, besides its heavy industrial footprint, which you mentioned: the supply is dominated by Mexico. There have been some, uh, erratic words about Mexico from the people in the position to affect trade policy and foreign policy.
About one third of this demand (photographic film and paper) more or less evaporated in the 2000s. You don't see that on the price chart, so I don't think you can seriously argue that the price is dictated by industrial uses.
I would say that the late 1970s reflexive silver bubble revealed magical thinking about silver which isn’t common with fiat. We know that big names rode the bubble on the way up, and made more on the way down. I think we can talk about meme pricing in the same way.
There's debt in dollars and euros, so people actually need to obtain dollars, euros etc. to avoid losing their collateral.
That isn't the case with silver or gold, for the most part, and what are you really going to use them for, now that there are so many excellent rust-resistant alloys?
Knowing all the molecules in it might be only a minor step towards actually making it, especially since some inputs of production might not be present in the final product.
Maybe in the future people will focus on solving problems some AGI can solve better to keep themselves in shape, like how exercise is a modern invention
