How about making some research on what fusion actually is?
That you are comparing it to J20 and Mars landing shows that you probably dodnt even know what fusion is

I recommend starting with fission and then transitioning to fusion

J20 and other 5th gen fighter jets are comically easy in comparison

It's only seen as harder because aerospace has had heavy R&D for almost a century whereas fusion is "relatively" new and seriously underfunded in comparison. Once significant net power fusion is solved in several decades, then it will be considered "easy" in hindsight. In the meantime, I completely agree with the fission argument. China has the most diverse and developed commercial nuclear industry in the world. It's not the most advanced in everything, but in the commercial realm, it is far ahead in some of the most important tech, specifically liquid thorium nuke tech (MSR - Molten Salt Reactors). Advantages are...

• can be closed cycle
• FAR FAR FAR less radioactive waste than 3rd generation uranium powered reactors
• FAR FAR FAR less dangerous than 4th gen Uranium/Plutonium breeder reactor tech
• burns up well over 99% of the Thorium fuel
  • over ~80% of the nuclear waste are fission products that decay almost completely within 20 years
  • remaining ~20% are all actinides that decay to background radiation level within 300 years, not thousands
• passively shutdown
• operate at near atmospheric pressure
• meltdown proof
• can be FAR MORE price competitive than coal
• could be bombed and destroy the containment and it would still passively shutdown
• Thorium is major by-product of rare earth production which is currently considered a waste by-product
  • instead of being a waste by-product, it would become basically free fuel
• Thorium reserves enough to supply power practically forever

It is literally like the holy grail of power sources. China began heavy R&D into this back in 2015, led by Jiang Mianheng, yes that Jiang Mianheng, the son of Jiang Zemin. China accelerated R&D around 2015 when they pushed to have the first commercial reactor by the early 2030s. I encourage research into every single viable nuclear technology that exists, simply for knowledge accumulation. However, this should be the primary focus because it is the best long term solution. Once they solve the materials problem related to corrosion with these Thorium reactors, it could usher in cheap unlimited power for China and would simultaneously solve a large number of other problems such as...

• energy independence
• pollution (air, water, soil)
• water shortages (economically viable desalination)
  • desertification
  • food independence

This is the single most important technology China would have. Yes, I even included desertification and food independence on my list. We are talking about energy costs that would be in the neighborhood of 1-2 cents USD$ per kWh. In other words, the power would be almost free. When you have nearly free power, anything is possible, including large scale desalination, pumping of that water over vast distances, and the associated advantages, like growing food. Although I don't think desertification is such a threat anymore since China has long reversed the desertification trend

You can even mine bitcoins for nearly free using this low cost energy. It is like printing money for free?

Yes cheap energy is revolutionary. Many things that we have technologies already available are not used due to.not being cost effective because they use too much energy.

If China manages to have svery low energy costs then the whole industry and R&D will have a fundamental change for the better.

So so many things are not used due to high energy costs..

And your pretending to be a nuke physicist? 30 to 40yrs huh? So what's happening exactly in the next 30 to 40 yrs Mr Expert?

Since you said "ALWAYS" 30 to 40yrs, after this 30to40 yrs, it will be another 30to40 yrs right? that should take to almost a century. Like I said, just say century, it's cooler, makes it more impressive!

He has a point. The ITER fusion project is the premier international fusion research collaboration and their schedule lists first plasma by 2035, which will probably be delayed as all such project usually are. They expect some kind of net power fusion reactor by sometime in the 2050s. That's just a prototype they are talking about that can achieve net energy. An actual rollout of a commercial scale fusion reactor would come after that. Now we are talking about the 2060s...or later.

Not really. There's no monopoly of miners. As power costs drop, it would draw more miners into the market and increase the global hashrate. That would simply make all existing miners mine less coins as the pie expanded. You would get that initial profit at the very beginning, but as number of miners increased and they all had access to the same cheap power, it would eventually become unprofitable to mine at some point. That's why you have to upgrade mining gear every year or so, depending on how much the hashrate increases. Even if the power cost was $0, this would still happen.

Japan will have to apologize and then pay $$ to other Asian countries including China and Korea for what they did during WWII. But the problem is that Japan is crumbling economically, and they have US$1 trillion worth of US treasuries that is about to depreciate in a big way.

It's too late for Japan to make amends. The Japanese generations have been successfully brainwashed into believing they were good Samaritans who were only saving Asia from colonial domination. Their "sacrifice" and getting nuked as a result is the dominant narrative in Japan.

I saw a Japanese news channel's tweet about Chinese Space achievements and decided to read the comments. Suffice to say... the Japanese netizens do not like it, in fact I think they do not like anything China at all. Not much you can do about it, especially the Nanking massacre deniers that I saw on another social media site.

@KampfAlwin bro let them have their say, I pitied the Japanese, being Asian they had the capability to do the same and choose not to, from hero to zero, now they're lamenting the fact that they should had done it before. Bro all this negative remarks (together with the Indians) are born out of frustration, jealousy and envy. Now it is also happening in Europe and the US, they're perplexed they were misinform by their media, they thought the Chinese still lived in caves..lol

It’s not just the Japanese. If you look at citizen comments from Korea, Vietnam, Philippines, etc... not many positive things about China.

China needs to slowly and gradually build up its softpower.

Fusion has been researched since the 1940s. Over 70 years already. It is damn hard.
