It's all pretty much nonsense from a chip perspective.

Only a tiny fraction of the world's chip output is on cutting edge nodes. What makes the world go around is everything else that isn't cutting edge. The much older, more mature nodes. 

There are strategic commercial reasons behind China not having access to cutting edge nodes so the most likely outcome of hostilities is old-fashioned, ehem, 'anonymous' physical destruction, a la Nord Stream, for example and the bulk of our telecommunications runs over undersea cabling too so that is guaranteed to get the snip if things go wrong. Satellite communications will also be interfered with. 

That would see a lot of already fabricated chips with very little to do. 

Sanctions have only accelerated China's chip efforts and determination and, as we move beyond silicon, new solutions will come to market (phototonics are showing promise). Possibly for highly specialised fields first but 'kill switches' are simply spanners in the works when it comes to fabrication. 

Apple took a huge risk in putting all its chip related eggs into one basket mostly in Taiwan. It's paid off so far but the risk (political, economic, natural disaster or otherwise) remains and they are seeking to change that slowly. A wise move. 

This is one area in which we can agree. Telling China that we’re not going to sell you the most advanced chips is just going to spur them on to spend a few dozen more billion on figuring out how to do it themselves. China is not Russia. Russia hasn’t the talent or money to compete. China, even with its current economic problems, does.

I haven’t see this on my wife’s new M4 iPad Pro. Still waiting for mine though. It will be interesting to note whether this effect can be seen through the nano surface of mine. I’ve been reading a lot of reviews and use tests of the new models, some who have already put extensive time in them. None of them have mentioned this. Considering that a lot of the reviews have been done by artists, who would, I would expect, examine their work, and therefore the display, quite critically, I don’t see this as a problem for anyone. When people look for problems, they can always find something, even if that something isn’t relevant to users.

My wife finally set hers up. The first thing I notice is that the screen colors are different. When compared, my M2 looks somewhat magenta and the new M4 looks green. Very strange. Even when I set both to reference mode which should put each in its calibrated setting, the difference persists. What’s strange is when I took a picture of both on my iPhone 15 Pro Max, the green one comes out more magenta and the magenta comes out more green. That, I can’t explain.

otherwise, the keyboard is absolutely great. Even with the screen angled all the way back, the function keys are easily available. The trackpad is sensitive and works smoothly.

the Pencil pro is weird in that the haptic feedback feels pretty real. I wasn’t actually expecting that. Some of the features such as the twist motion won’t be useful if you’re not an artist or calligrapher, because it takes some skill to use properly. But, it does what it’s supposed to. I’m not patiently waiting for the new version of Procreate so I can test what they’ve done with it.

the only thing I don’t understand is the color difference.

so as far as I can see, it’s looks like a very nice upgrade to everything. It’s really notebook-like now. I’m hoping Apple will show something innovative on the OS front this coming June 10th.

It looks like a calculation error causing blown highlights in blues. 

Software, apparently. A relatively simple fix, it looks like.

I think many commentators have missed the point.
Quantum Dots would provide a brighter screen without a need for more power.
Therefore, for a given brightness, the iPhone would use less power.

Quantum dit technology isn’t a panacea. Samsung uses it for some Tv screens, but not for their phone, tablet or computer OLED displays. It’s very difficult to get that tech down to the needs of small displays. Phone and watch OLEDs are a different technology that that for larger displays. If it could have been easily done, then it would have been done already, but it’s complex and difficult in smaller displays with their very high pixel density, much more dense with far smaller pixels than in the much larger Tv screens.
