At the 2018 Deconomy conference in Seoul, South Korea, Buterin and Wright were both booked as speakers, and the sparks flew. During question period for a panel that included Wright, Buterin (according to audience video from multiple angles posted to social media) stood up in the audience and asked, “Given he makes so many non-sequiturs and mistakes, why is this fraud allowed to speak at this conference?” The audience, video shows, went wild.
Buterin also live-tweeted the talk.
