The difference is that water vapour is a greenhouse gas. IIRC the net warming effect of clouds is a function of altitude.

> Agreements aren’t worth the paper they’re printed on.

Pretty much. They are only as effective as the body trying to enforce it. The entire point of being a sovereign nation is nobody can force you to do anything. Now it is in a nation's self interest to not violate agreements and get along nicely, but sometimes the calculus changes and the punishment may not outweigh the benefits.

Depends on your definition of knowing. Sure, we know it is predicting next tokens, but do we understand why they output the things they do? I am not well versed with LLMs, but I assume even for smaller modles interpretability is a big challenge.

> Is a Tesla any worse than you at spotting booby trapped roads

That would've been been the case if all laws, opinions and purchasing decisions were made by everyone acting rationally. Even if self driving cars are safer than human drivers, it just takes a few crashes to damage their reputation. It has to be much, much safer than humans for mass adoption. Ideally also safer than the competition, if you're comparing specific companies.

Oh I was referring to the response of the cones itself (not the response after the opponent process). I was under the assumption there's no measured curves for the responses after having gone through the opponent process in the neuron-layer(?), so the graph and caption were conflating the response of the cones with color matching functions.

Looks like an interesting read, thanks for sharing!

>> yielding this spectral response: [graph with negative values]

That's what I gathered from spectral response. Usually spectral response in this context refers to the responsivity of the cones. Even when accounting for 'brain subtracting green from red' (which I assume comes from the opponent process theory) the following graph has nothing to do with it. The captions too read 'Yes, this results in red having negative sensitivity @500 nm', implying the red (L) cones have a negative sensitivity to cyans — which, again, is not really the case.

> Because there’s a lot of overlap between the red and green cones, our brain subtracts some green from red, yielding this spectral response:

No, cones do not produce a negative response. The graph shows the intensity of the primaries required to recreate the spectral colour at that wavelength. The negative implies that the primary was added to the spectral colour to match it with itself, instead of adding it with the other primaries.

I was not aware of this. Also judging by this and the sibling comments, it looks like the momentum didn't die despite Google's apathy. Hopefully the fact that their own team is now developing the rust port, as well as the growing support in other platforms, is enough to make Google reconsider its choices.

For me, there's a certain aesthetic to 1-bit bayer-dithered images, as well as images with visibly big coloured-halftone-dots, that makes it feel both retro and modern at the same time. I want to call it neo-retro, but I feel like that term already exists.
