The uncomfortable truth is this, every one of us uses their products, in one way or another. The electricity that lights our homes. The fuel that moves our cars, buses, ships, and airplanes. The concrete, steel, plastics, fertilizers, medicines, and electronics that make modern life possible. The food system, the construction industry, global logistics, heating, cooling, data centers, all of it is built on energy supplied largely by fossil fuels. Those 32 companies did not emit carbon in a vacuum. They extracted and sold what the world demanded, and the world governments, industries, cities, and individuals bought it. This does not absolve these corporations of responsibility. Many knew the consequences decades ago, funded misinformation, and delayed the transition. Accountability matters. Regulation matters. Transparency matters. But pretending this is only a “them” problem lets the rest of us off the hook too easily. Climate change is not just a story of bad actors, it’s a story of a system we all participate in, willingly or not. We live in cities designed around cars. We inhabit buildings that require energy intensive materials. We rely on global supply chains optimized for cost, not carbon. Even the devices we use to read climate reports depend on fossil fuel powered infrastructure. Real solutions won’t come from scapegoating alone. They come from: - Changing how energy is produced, - Redesigning how cities are built, - Rethinking how we move, consume, and invest, - And demanding both corporate accountability and systemic transformation. Yes, 32 companies sit at the center of the problem. But 7+ billion people are connected to it. If half of emissions come from a few firms, the opportunity is just as clear: changing the system upstream can change everything downstream. The transition is possible, but only if we stop pretending we’re not part of the story.

Video surveillance is not the solution. PC camera field of view is pretty narrow. I watched YT videos of of people standing near the screen and use their cameras and AI assistants to cheat during online exams. This cheating creates such erosion of ethics in society, I am glad someone noticed and doing something about it.

Will we be able to get our existing credits back?

With the stupid trade tariffs to China on electric cars, government takes away my opportunity to buy a new $10K electric car. Protecting local car brands while punishing 330 million citizens...

Well, from the looks of it, the walls have an interior cavity, where technically you can run pipes, conduits for plumbing/electrical/network, etc. However, it needs to be done during the "printing" process, otherwise you will not be able to reach within at those wall heights unless you start cutting holes in the wall. I do not see a practical way to do this, while the machine is running. If you cannot do it during the wall printing, you have to run everything on the face of the wall (which is not visually attractive). You cannot cover pipes running the whole height of the wall, at that point it just becomes silly (why did we even "print" the walls if we have to deal with all this??). Those concrete ripples (as you said) cannot be covered by paint, you have to either grind it or fill it to receive a flat surface. Both application is very time consuming and costly. Again if we have to do all these additional steps (which is not part of regular construction), what is the point of "printing"? Construction in general is very complicated for automation, and almost every building is a unique prototype that has never been build before (even if you use the same building plans, the direction, soil conditions, site conditions, location will make each of them a unique build). Therefore, construction industry will be one of the last industries where we will see automation in a meaningful way. In my opinion, to automate construction and bring down the cost, we would need humanoid robots with generic AI that can use existing techniques, tools and materials just like a human would do. They do not need to rest, and keep going 24/7 with much greater precision. Until we get those robots, these 3D print buildings are a gimmick for research money at best and investor fraud at worst.

The only thing 3D printed in these are the walls and part of the structure. There are hundreds of more materials and systems that goes into a house. And guess what, the cost of walls are minuscule compared to the total cost of a house (hence the price of the houses). This technology is a gimmick at best in its current form. Also as an Architect, those lines (from each print layer) on the walls are horrible. I cant imagine how much dirt/dust will be there (it is very difficult to clean as well). You have to finish the walls for a smooth surface to make it livable, which adds additional cost.

I understand the kind thought you have for a better society. However your suggestion do not solve the problem. When you have a limit (whatever that amount may be) on the federal loan guarantee, there is nothing to stop the next populist politician to just increase that limit arbitrarily. We need to understand, politicians have a single goal, and that is to get votes to get in and stay in the office. That is how they have their livelihood. Therefore, they are encouraged to promise more "free" (in your case, increase loan limits) to get more votes. The solution should be removing all the causes and stopping it to happen ever again. You stop the Federal Government guaranteeing the student loans. The whole argument of poor people not getting education is a bogus one. The program started at 1965. Higher education was doing great with much lower costs and affordability. Also, individuals should be held accountable for their own decision (good or bad) and live with the consequences. Once you start making unrelated people pay for mistakes of others, the whole natural order breaks and you end up with disasters like the student loan crisis that is gonna hit soon. If you get a higher education, that benefits you more than anyone else (by higher paying jobs). Therefore you should pay for your own well being (meaning taking the risk of getting a loan for a positive income return for the future).

God speed to the bottom of the ocean...

Who decides the cap? Some politician who has no skin in the game? Only way to deal with this issue is to put the schools and banks on the line for non performing loans. Basically stop federal government guarantee on the student loans.

It is clear that you do not in anyway know anything about construction. 45 cubic meter is nothing. I finished a student dormitory building, where I used a total of 22,790.5 cubic meters (yes, 22 thousand+) of concrete. It was a two block, 13 stories high, total of 3,000 student capacity structure. A regular concrete mixer hold 12 cubic meter of concrete (they can actually carry 13+, but regulations prevent them). I had 2,109 mixers worth of cement. Now think about the immense potential of that...

Any kind of a building incorporates literally hundreds of different components and materials. These 3D printers only print the walls of a building. Therefore they only "3D print" a single material out of those hundreds, in this example a brick wall. And they are not even structural since they do not have any kind of strength (lack of rebars) for lateral forces (earthquake?). The wall finishes are extremely rough. It will take way more effort to get them to a nice smooth finish. If you want to keep them as is, they become a nightmare to keep up, all those spaces between print layers will be filled so much dirt and you name it. It is false advertisement at best to consider these anything as "3D printed buildings".

I think it is about time, consumer protection laws start including sections such as "if you stop servers for whatever reason, you shoul open source the service". There should be responsibility for these companies for their products

Well I would love to see a new station from Russia, however with their current and foreseeable economic troubles, good luck...

Having ability to connect internet, regardless of your geographical location and country will also allow Billions of suppressed people to have free internet access that is not censored by their despot/fascist/communist/dictatorial governments. I believe this is going to be the biggest social positive of these new commercial satellite internet services.

My point exactly! Can you imagine not getting a chance to see the amazing background which is the Coruscant in Starwars, or those amazing environments at The Lord of The Rings? I don't think so. Blurring everything other than whatever is the focus is a great idea for fascist film making, I suppose this was discovered in 1940s?
