They don't attempt to jam, the frequency is just little bit off to minimize damage and it's very short time. They just test the system to verify that it works.
What this reveals: Russian early warning satellite constellation has also GNSS jammers they test periodically. They can jam whole continent from single satellite. They have six satellites in Molniya orbits.
Because we want to write correct code. We want to verify the absence of many types of errors where amateurish language war stuff like Rust vs C does not even scratch the surface.
I would propose that we change your original statement "Ideally neither C nor C++ should be used when security matters." into:
"Ideally people who don't care about secrurity should not write code when security matters."
Can we agree that this is better than talking about programming languages?
Explain to someone like me who uses C in safety-critical software in aerospace and defense why not?
For me, choosing the language is not enough. It's the tooling that goes far beyond the language that is important for safety and quality of compiler and runtime. C has very mature tooling options. So does ADA.
The first SoC including Neural Engine was the A11 Bionic, used in iPhone 8, 8 Plus and iPhone X, introduced in 2017. Since then, every Apple A-series SoC has included a Neural Engine.

Even in the wonderland of fiber, South Korea, fiber to the home has slowed down and fiber to the building is common. Korea Telecom still has lots of coaxial setups they stretch into gigabit speeds using 1:N connections. Gigabit penetration in Seoul was still below 50% few years back, much lower elsewhere.
Btw. Fiber has no latency advantage. What you need is servers at edge in both use cases.
Carmack briefly mentions 5G and streaming games. I think there is good economic reason for the 5G gaming is eventually coming (it may take some time) because low latency enables it.
If you think about the price of gaming PC or console, there is huge discrepancy between the budget of hardcore gaming enthusiast and casual gamer. It would be nice to get $5000 gaming tower in every house, but you don't. Many casual gamers would rent $5000 - $10,000 worth of gaming hardware for few hours a week it was simple. Only way to get bleeding edge high-end gaming to masses is to put GPU and some other parts to the edge (or at least within the same city) and stream or partially stream the game to cheaper computer device and screens.
Consider $5,000 worth of bleeding edge hardware that costs $1/hour to run. If you rent it for $8/hour, and it only sells for 5 hours per day for gaming, the HW pays itself back in 5 months. It could be rented out for other stuff in the meantime. Cloudflare, what do you think?
I could see a market emerging similar to school VHS/DVD/Game rentals. There is limited computational resource near you and you can rent it for gaming. If all is taken (weekend evenings) the 'shelves' are empty. On working/school days and hours you get the same thing cheaper.
It probably happens in Japan, South Korea and Nordic countries first.
Carmack makes good point about VR in the beginning. For people who live in tight spaces VR can be way to do conventional things like watch films and YouTube. This kind of conventional use could be what bootstraps VR markets.
VR headset tech is in a weird situation where none of them is really good enough, but when you test the best in the market it destroys the enjoyment you get from previous generation. I tested 20 minutes $6000 Vario VR-1 where the market is professional use and now anything consumer grade feels like total crap.
It's not rewarding bad behavior when you take it into account in the deal. Moralization is useless when you do business with different cultures. When you notice something what would be out of ordinary in your culture, you estimate the cost and find out how locals solve it. Different cultures have different kinks and people living there know to adjust to them. It can be fun to figure out how other cultures function.
From a naive Finnish perspective you could see American business culture as dishonest. People lie all the time and promise things that are false and you need massive amount of legalese or they fuck you over. When they say something, you can't trust it as much as you can trust a Finn (or Swede). American way is to lie to your face in pre-negotiation but then be truthful to the legally binding agreement. Germans or Belgians are more truthful beforehand and they stick to deals better without legal enforcement looming over them, but require more detailed written deals than Finns. Who is right? Should we punish Americans for their behavior or adopt their culture?
Of course not. You must understand that that the level of acceptable exaggeration, overpromise and bullshit and trickery is strictly culture dependent and relative. Someone is dishonest if they "lie this amount above average" in their cultural context. After you make an adjustment, you know how to get the truth.
Chinese manufacturers have the capability to stick to standards, take responsibility and deliver high quality stuff. It's just more dependent on personal relationship. Just placing an order has less trust as default. Either you develop "quanxi" with your suppliers or work trough some third party that understands both worlds. Third party understands what you need and knows how to get it from the Chinese suppliers because they have a relationship.
Chinese pay the cost that comes with their business culture. They can't network as fast as you can in open western cultures with more default trust between strangers.
I have observed the same but I have observed the exact opposite in academia and academically oriented corporate R&D in complex technical fields.
People with academic background can surprisingly humble intellectually. They may be arrogant when defending their point of view, but if they come up with a new thing they don't know about, they admit it even if it's common thing. By constantly asking simple questions every time they can't follow up something they are able to learn constantly.
