I don't think you can cut that since currency powers will stay as long as USD is in high demand
Why is the USD in high demand? It's because America has global political and military dominance. (It used to also have tech dominance, making it so that countries needed the USD to buy its world-leading tech but that is dying or dead in most places replaced by China.) If China overtakes both, and it's already far superior in manufacturing most things (soon to be everything), then why does anyone want the USD? If China prefers or demands non-US currencies, what value does the USD have if it cannot buy what everyone wants, which is made in China? Then how will the US react to prevent countries from not accepting the USD if its political and military powers are eclipsed by China? This is the recipe to cripple America's root of power, which is the USD and the sanctions made possible by its reserve currency status.
and no other currencies can replace USD in global scale.
Reread my first post. Nothing needs to replace the USD; the world does not need a reserve currency. The reserve currency status of the USD is a power that the US unnaturally gave itself after WWII. Without it, international trade would be a little encumbered, but it would make sense. Every country would have to produce something useful for its currency to be useful in trade. Right now, you have countries that are consumers and countries that are producers, with the consumers basically being leeches trading little more than freely printed paper money for real goods. This is not a balance; this is the remnant of colonialism and a result of what the Western winners of WWII imposed. It can stop completely and the world would be better, fairer, more balanced and the only people crying about it would be the Anglos who used it to rob the world.
While US has the best geography in the world
Not really. Geography is based on politics. Are your neighbors your friends or are they your enemies? If you are strong, no one dares to be your enemy. If you are weak, everyone looks at you like a piece of meat. If China blows past the US, we can easily turn Mexico (and apparently Canada was well as long as they remember how Trump and MAGA treated them) into enemies of the US. With the power of the USD diminished, America will struggle to fund any military. Then, China sells our B level military tech to Mexico, Canada and Cuba, with Mexico starting border issues all the time because they remember that everything from Texas to California should be theirs, Canada harassing the US over little islands and fishing rights, and Cuba constantly buzzing the now dilapidated USN just 40 miles from Florida, you will have the US in the worst geography possible, just like that.
protects them from any harms that would permanently reduce their military powers.
All military power is relative. To reduce someone's military power, all you need to do is develop yours faster than theirs, like China is doing right now.
This is just an open admission that China has many more talents than the US. Anduril's CEO has no idea that the life standard of China's researchers has improved substantially in the past 10 years and they are richly compensated and handsomely rewarded for their achievements in China. Furthermore, China has some of the world's most innovative and dynamic research programs and the most advanced research facilities, far more attractive than the potentially hostile workplaces in the US. Yeah, a few Chinese experts may go to the US anyway. But China's talent pool will remain substantially larger. Rest assured, Anduril will attract far more India talents than Chinese ones.
The dude is such an ordinary dude in the worst way possible. His language shows minimal education and his plans are rooted in redundancy (let's steal global talent) or factual inaccuracy (China doesn't care about its single men so they'll send them to fight our drones). I really cannot understand how he is the CEO of anything other than like a fast food joint.
Why brain drain China, when we have literal list of Hanjians already volunteering to brain drain themselves for the US? I'm sure they are smart enough to work for the likes of Anduril and Palantir.
See, the Chinese people in the US either excel in tech or they hold up hanjian signs. I have almost never seen one who does both. Alexandr Wang is extremely rare. You cannot usually fool intelligent people into pouring their lives into injuring themselves and the global brand/image of their genetic being.
