Evin McMullen, CEO of Billions Network, has expressed concerns that AI agents could significantly disrupt the advertising revenue models of major tech companies like Google and Facebook. McMullen's perspective aligns with previous statements from Cardano Founder Charles Hoskinson and Cloudflare CSO Stephanie Cohen, who have also highlighted the potential threat AI poses to traditional digital advertising frameworks. The growing capabilities of AI agents to perform tasks traditionally handled by human intermediaries could lead to a shift in how advertising is conducted, potentially impacting the core revenue streams of these tech giants.
