I watched Musk's latest interview video today, titled: Elon Musk: A Different Conversation w/Nikhil Kamath. You can search for it on YouTube or check the comments section. One of the viewpoints that really shook me was, 'When AI and robots make' scarcity 'disappear, money is no longer necessary, and the only standard for measuring real and fake currency is energy - BTC!'! '' From the assumption of the future, if productivity is infinitely close to free, the meaning of currency will sharply decline. This thinking pattern seems to be Musk's innate first principles thinking. We know a fundamental logic in economics: the meaning of money is to allocate scarce resources, and if scarcity does not exist, the allocation mechanism itself will disappear. Just like the civilization mentioned in the video "The Culture" by Iain Banks: everyone doesn't have to worry about food and clothing, they have whatever they want, and in the end, currency will be eliminated. However, Musk continued to emphasize a particularly crucial point: "Even without money, there will still be a fundamental currency, and that is energy In fact, this sentence is very important and can even directly explain why Musk has long been bullish on BTC: Energy is the ultimate currency Because: You cannot 'legislate' to create energy You cannot print energy by printing money Energy is always scarce Energy is the underlying logic of the physical world All production relies on energy In a world where everything is automated and productivity is infinite, the only truly scarce thing is energy. So Musk concludes that BTC is an "energy based currency" that will be the ultimate form of currency in the future The value of BTC is anchored to the 'energy cost in the real world' Mining machines need to consume real electricity Electricity costs cannot be falsified The government cannot 'print more computing power' Cybersecurity relies on actual energy investment So essentially: BTC=Energy → A Form of Monetization Although many people criticize PoW for its high electricity consumption, from Musk's perspective: Energy consumption=network security Energy input=value endorsement If the symbol system of money collapses in the future, the remaining currency will be: energy itself → BTC And Bitcoin happens to be the first system in human history to digitize energy onto the blockchain. This is the world's richest person's underlying philosophical understanding of BTC. To be honest, I was deeply shocked! So in my understanding, a decentralized energy currency system would be more stable than a central fiat currency because fiat currency can be expanded through "legislation". But energy cannot. Energy currency is more difficult to manipulate and more resistant to inflation than credit currency. So in the future, society may no longer need the US dollar, but it may still need BTC. This is disruptive to the traditional financial system. So cherish your BTC and buy more at low prices. If you agree with Musk's underlying monetary philosophy
