CoinVoice has recently learned that Ethereum founder Vitalik responded to X user @yishan's tweet asking, 'What are some things you used to believe in strongly but changed your mind about after learning more?' He stated: I no longer focus on mathematics and cryptographic protocols like I did 10 years ago; now I use mathematics to make rough initial guesses and try to avoid the worst-case scenarios, rather than explaining average-case behavior.
Vitalik's interest in economics is also waning. He wrote: I spent a lot of time in the first five years of the crypto world trying to invent a mathematically provable optimal governance mechanism, only to find that what I was looking for was impossible to achieve. The most important variables that determine the success or failure of existing flawed systems in practice (often the degree of coordination between subgroups of participants, but also factors of 'culture') are variables that I did not model or consider at the time.
