There are indeed hard limits to chemical rocketry, and we mostly hit them after a decade or two of work by people with pencils and slide rules. Computers might be a better analogy. We started designing computers without the aid of other computers. We made very rapid progress on architecture and semiconductors. We’re now completely dependent on computers to help us design future ones, and despite all our efforts and hundreds of billions of dollars in investments, our rate of progress has slowed to a crawl and we seem to rapidly be approaching the end game. Dennard scaling has been done for 15 years. We can make wires that are smaller but just proportionally worse. We can use more silicon area, but then latency and power consumption get proportionally worse. A super clever hyper optimizing AI might push a couple things forward a little bit (or more likely wind up at the exact same destination slightly earlier than we other wise might have), but there’s no compelling reason to think it gets to design computers that face different constraints.
