Ethereum co-founder Vitalik Buterin warns through X that if AI lacks human oversight, no matter how fast AI evolves, it may ultimately slide toward a direction that is difficult for humans to control. (Background: '1-hour withdrawal' is more important than decentralization! Vitalik's L2 strategic thinking has changed) (Background supplement: Was Ethereum almost not born? Brian Armstrong revealed: once invited Vitalik to join Coinbase, but missed due to U.S. visa issues) In 2025, the two torrents of AI and blockchain are accelerating forward simultaneously. Just as the market is hotly discussing the prospects of AGI (Artificial General Intelligence), Ethereum co-founder Vitalik Buterin warns through X that if AI lacks human oversight, no matter how fast AI evolves, it may ultimately slide toward a direction that is difficult for humans to control. Many AI developments attempt to move toward 'autonomy' as much as possible, which indeed frustrates me, as actually creating more pathways for human input can not only generate better outputs (both currently and for a long time in the future) but is also more beneficial for safety. In the medium term I want some fancy BCI thing where it shows me the thing as it's being generated and detects in real time how I feel about each part of it and adjusts accordingly. — vitalik.eth (@VitalikButerin) August 11, 2025 'Human feedback mechanism' takes shape Vitalik Buterin emphasizes in the post that AI should not be designed solely as a fully automated 'agent,' but rather needs to have the 'editing' capability that can be corrected by humans at any time. Open-weight models (open source) allow developers to scrutinize algorithmic pathways, while the 'human feedback mechanism' can ensure that final decisions return to human hands. He particularly reminds us that in high-risk scenarios, such as financial transactions, only by including humans in the process can a dynamic balance between efficiency and safety be achieved. At the same time, Vitalik's notion of 'collaboration' also points to brain-computer interfaces (BCI). While a visual future is certainly eye-catching, in applications such as medical monitoring, learning enhancement, and even financial trading, data privacy and ethical boundaries still need to be clearly defined. The tug-of-war of Ethereum's decentralized governance However, it is worth noting that despite Vitalik's repeated emphasis on the importance of decentralization and open source, the current crypto community believes that the Ethereum Foundation is becoming increasingly centralized. First of all, the community previously raised doubts, believing that Vitalik Buterin holds too much power in the Ethereum Foundation, even having a veto vote. The foundation has also avoided discussing its voting rights allocation, leading to community concerns about its governance transparency. Although the Ethereum Foundation has undergone organizational restructuring, such as Aya Miyaguchi taking over as chairperson, and the appointment of Hsiao-Wei Wang and Tomasz Stańczak as co-executive directors. Although this move is seen as a decentralization of decision-making responsibility, the community still worries that power is concentrated in the hands of a few core members, which contradicts the principle of decentralization. Vitalik Buterin hopes AI returns to the subjectivity of 'humans,' but the current state of Ethereum reflects that 'humans' sometimes also means a few decision-makers. Currently, with a large influx of institutional funds into ETH, some holders are also concerned that the financial and governance model of the Ethereum Foundation may be hijacked...
