Ethereum co-founder Vitalik Buterin has emphasized the role of Grok, an AI tool, in maintaining honest discourse on the social media platform X. Buterin noted that Grok's unpredictable responses challenge users' biases, often leading to a more balanced perspective rather than confirming preconceived notions. This unpredictability, according to Buterin, helps foster a more truthful and unbiased environment on the platform.
