Deep Tide TechFlow news, on December 15, Ethereum founder Vitalik Buterin responded to X user @yishan's tweet asking 'What are some things you used to strongly believe in but changed your mind about as you learned more?' saying: I no longer focus on mathematics and cryptographic protocols as I did 10 years ago; now I use mathematics to propose rough preliminary guesses and try to avoid the worst-case scenarios, rather than explaining behavior in the average case.
Vitalik's interest in economics is also waning, he wrote: I spent a lot of time in the first five years of my crypto journey trying to invent an optimally governable mechanism that could be mathematically proven, but ultimately found that what I was looking for is impossible to achieve. The most important variables that determine the success or failure of existing flawed systems in practice (often the degree of coordination among participant subgroups, but also cultural factors) were variables I did not model or consider at that time.
