Source? Or is it just a matter of "it has the same shape as a western car, and a steering wheel = omfg IP theft"?

There are valid commercial reasons not to go through a forced sale with a ticking time limit, which will inevitably carry a steeply discounted price. Rather than getting robbed, it makes sense to hang on to the company and take profits from the rest of the world.

Funny thing is, those Chinese drones are being heavily used by Ukraine, because they're more reliable than US-made drones. In 2023, Ukraine bought about 60% of the global supply of DJI's Mavic quadcopters.

It's gonna get pulled from app stores for "promoting antisemitism". You don't need to be the Kwisatz Haderach to foresee this.

As I understand, using VPNs to access will be illegal in principle, and the VPNs can be on the hook for stiff penalties.

In practice, it will depend on how zealously the government plays the cat and mouse game. Kind of the same situation as with China and VPNs that bypass the Great Firewall (ironic!).

I mean, you can use that approach to denigrate pretty much any activity people spend time on.

How much of the coal in a blast furnace is actually necessary for the carbon impregnation, as opposed to supplying the heat via combustion? Steel contains only a few percent carbon by weight, so it doesn't seem like much carbon is needed (not to mention that the carbon in steel is essentially sequestered).

I think those use normal VCSELs. To justify using PCSELs, maybe it would be lidars for long range sensing, like range finding over dozens of meters or something.

This is a really neat technology that Noda (the author of the article) has been plugging away at for decades. The main problem, from my understanding, is that people haven't been able to find applications.

We already have conventional laser diodes that work extremely well, they're not that bright but bright enough to make laser pointers, disc read/write heads, etc., which are applications where miniaturization is important.

On the other hand, in industrial applications like cutting steel, we have fiber lasers. Those are about the size of a briefcase, compared to the photonic crystal lasers in this article which about a centimeter. But they can reach incredible brightness, about 1000x the output power of the photonic crystal lasers (and about 1,000,000 times that of ordinary laser diodes). And in industrial applications you don't really need the laser to be miniaturized (especially since the power source itself will be a chonky piece of equipment).

So somehow, right now this neat tech is falling into the cracks. One day, I'm sure someone will find the perfect application for it, though.

Edit: the potential application that people are most hopeful about is lidar; if, in the future, lidar gets integrated into consumer electronic devices like cellphones, then photonic crystal lasers will probably prove their usefulness.
