Ethereum founder Vitalik Buterin likened Ethereum to a "spreadsheet with macros" during a Tim Ferriss interview on March 12, 2021. Buterin emphasized Ethereum's nature as a general-purpose blockchain, contrasting it with Bitcoin, which he described as a static spreadsheet where users control specific cells. He highlighted Ethereum's capability for accounts to execute code and interact autonomously based on pre-programmed rules.Buterin underscored the autonomy of applications built on Ethereum, noting that once deployed, they operate independently of their creators. This ensures that applications run strictly according to their rules without external interference, showcasing Ethereum's potential for decentralized and self-sustaining applications.
