    lol. That whole thing was propaganda. First of all, the 4F2 process isn’t better than the 6F2 process. 4F2 is worse! 4F2, just means they’re being forced to build the chip vertically in more steps because they don’t have access to ASMLs most advanced lithography machines. Because they can’t pack more transistors into a smaller space by making them smaller, they’re being forced to build them vertically, which requires more layers. And more layers means more chances for microscopic mistakes. And that’s the case! Their yields are abysmal, only 30% yields, while Samsung and SK Hynix typically get 70% yields. And what do 30% yields mean? It’s means the process isn’t commercially viable. The only reason it even exists is because the Chinese government forces it to. In order to be commercially viable, their prices would have to be much higher than everyone else’s, in which case it’s a huge waste of time. Granted, the Chinese government might flood the world with these chips as a loss leader, but mostly they’re just making them to satisfy the Chinese government’s own need for chips. They probably won’t leave the country in any significant number.

    The large tech companies (Meta, Microsoft, Google, Amazon) all know that software companies are going to go bankrupt. People will start creating things like Windows with LLM. Windows and software is obsolete. So these big companies that are sitting on hordes of cash, and know their days are limited, need to make a pivot. They also know that all the countries of the world are deeply in debt, and inflation is going to continue. Cell phones are becoming expensive, and will only get worse as inflation continues, and countries start devaluing their currencies. So the push is going to be (and Elon Musk said this flat out on Joe Rogan), new inexpensive devices will replace cellphones. They wont have a CPU or much RAM, because all the apps will be cast from Data Centers. The world will return to the terminal servers of the 70s. So Data Centers will have a use, for steaming all the apps. But the other thing is that the worldwide electrical grid is old, and can’t handle all the new power that’s needed for the Data Centers, and Electrical Vehicles. I saw a millionaire call the rebuilding of the Electrical Grid that’s taking place a modern day Industrial Revolution. So, the bigger part behind each data center is going to be the SMR (Small Modular Reactors) The small modular reactors are built in the same style as the nuclear reactors inside a nuclear submarine, or an aircraft carrier. They are mass produced, built like interlocking Legos, self contained, and run for 20-30 years without needing any more nuclear fuel added. They will power the data centers, and MORE IMPORTANTLY, they will be connected to the grid! So these large companies like Microsoft who bough the 3 mile Island reactor, will become hybrid tech companies, selling app subscriptions, cloud space, utility companies, selling electricity back into the system. It’s also important to get the cost of electricity down using the SMR, because the average person is going to be a lot poorer in the future. Here you go, the full scoop, you won’t hear on the news.
