Everything in the world seems to be trapped in a 'self referential cycle': success and failure often intertwine on the same thing. Cantor once thought his set theory was perfect, but it was overturned by Russell's paradox; the mathematical logic building constructed by Russell and Hilbert, among others, also revealed cracks due to G ö del's incompleteness theorem. Ethereum rose or fell because of blockchain technology. I even predict that Elon Musk will experience similar ups and downs on 'first principles': he may climb to the pinnacle of technology and politics as a result, but he may also pay a price for it, such as Tesla's autonomous driving technology, which may be difficult to achieve due to its theoretical limitations
