You seem to have what I would call a mistaken idea: that Linus will "choose" his successor. He won't. The community will. Even if he recommends someone, the community will either accept or reject them (or do both). It is entirely possible that nobody can really succeed him (because he has a genuinely unique combination of skills, motivations, and contacts), so he will effectively have no successor. The structure of the open kernel project now called Linux will change.
I think that is just reality and anyone trying to "choose" his successor in advance of it needing to happen is just getting in early on the politics of the community deciding who coordinates core kernel development after Linus steps down. If that is even still a thing and it doesn't splinter. (There is a reasonable argument to be made that it has already splintered into the distribution kernels, and what we call the core kernel is just the working space for coordination between the splinters.) I think deciding succession in advance is pretty demonstrably a waste of time, and possibly even counter-productive, since the situation is likely to change between now and when the change needs to happen. I'm glad that Linus himself seems to be aware of this.
The US has been occupying an artificial position since the end of WW2, since it was the only developed country to not be basically destroyed. We are just living through the transition to a broader world economy. And listening to racist xenophobes rage about it.
Assuming you aren't a pro-china bot or shill, you seem to have a westerner's lack of understanding of the absence of political freedom because you have always had it. Propaganda about China being 100% evil is pretty recent - mostly the west has treated China fairly nicely even when China has acted badly because the western powers at the time understood that building and sustaining relationships is more important in the long run than any individual dispute. The weird thing is now China has grown up, it complains about being treated as an equal. China seems to want to be a leader but still with all the perks of being considered a developing economy. That's not going to happen. If China wants to treat a particular market in a protectionist manner (social media, cell phones, etc) nobody should be surprised when other countries do the same against them. That is normal international trade relations, not nationalism. It's when the two get conflated that things go badly.
You don't seem to realize that many (most?) people don't even know how to use a calculator properly. We are not talking about people like yourself who maybe can't do long division by hand, but people who don't even know what to do if you ask them to make change for a 20 for something that costs 18.62 and they aren't sitting at a cash register. i.e. they don't even know what subtraction really is or how to use it in a general context.
We're also pretty obviously not talking about using LLMs for "checking" one's writing. We're talking about people losing the ability to even form their thoughts into a coherent paragraph because they think all they are supposed to do is feed a prompt into an LLM. I actually totally agree that LLMs are very much the language equivalent of the calculator. We are still in the process of figuring out how to integrate them into everyday usage in a way that benefits the user more than it hurts them. I would argue it took a while to figure this out for calculators and we still don't get it right at the general education level.
The execs appear to also not understand southwest's business model. The boarding and checked bag rules were obviously specifically designed to make getting people on the airplane far far faster. (assigned seating and dealing with carry-ons is super slow). Southwest's business model was based on getting planes loaded fast and getting them back in the air. Presumably that meant they could service a particular passenger base with fewer airplanes. If they slow down their boarding, then they are just another airline without that advantage anymore. This does sound like new upper management just not understanding the structural strengths of the company.
Though honestly "no free check bag" has turned into "take a carry on size bag and check it at the gate for free because too many people are bringing carry-ons" for most airlines anyway. So I don't really know what this policy accomplishes other than selling more travel-sized toothpaste. I can see charging for more than 1 bag, but charging for the first bag just doesn't make sense because there simply is not enough carry-on space for everyone to bring a carry-on size bag. So the main impact is actually to just slow down boarding and increase the work the gate agent has to do. That sounds a lot like bad management - a policy that only appears to increase revenue because the trade-offs aren't being accounted for correctly.
