Cardano founder Charles Hoskinson lashed out at Ethereum co-founder Vitalik Buterin after Buterin warned that AI-driven mathematical discoveries could significantly undermine the stability of lattice cryptography within the next two years. Hoskinson called Buterin's remarks "unsubstantiated" and "highly speculative," arguing that his stance could hinder the transition from classical to post-quantum cryptography, causing severe damage to the cybersecurity industry.
