I agree that Moore's law is slowing down, but that isn't because scientists are stupid-it's because they are too good. Moore's law worked mainly because we were shrinking down the size of the transistor (the functional unit of a microchip) to fit exponentially more transistors on a microchips each year. However, they have gotten so small that the transistors do not follow the same rules of physics that normal particles, they are following quantum mechanics. This will open up a whole new avenue for quantum computers in the future and in my opinion it will quickly be able to solve hashes in a Blockchain to the point that is destroys NFTs and Crypto 👍. Also it's a good thing that development in transistor size and sheer processing power has stopped, since now focus is on other aspects of a microchip, such as efficiency. This is a very good thing as microchip technology development can be explained similar to a steam powered train. Instead of creating new power sources for a better train overall, we have been finding ways to put more coal inside the train to increase power and have hit a natural limit. Development for different architectures, is like using a different energy source for a train, for example the ARM chips in our phone are getting very powerful extremely fast and are extremely energy efficient compared to the processors in our desktop PCs. Hopefully we will continue making these processors more energy efficient and powerful, as soon everyone in the third world countries will want these devices and that energy consumption will add up quickly. As for sheer processing power, cloud computing has become very popular and effective in the past couple years for researchers, but I agree that it could be absolutely dangerous if someone hoards computing power to create a dangerous AI.
