Some Youtube influencers got money to share some bullshit about threats of AI for humanity in the near future & some other says they reject money, so DHH talk could be a marketing campaign for AI companies. It is called viral marketing , in viral marketing you convince reference group (or give money to the reference group) & reference group is convincing the other people
Honestly, it might be just a lie. Seems that there are people working inside his company that said they are not migrating things to Rust - only the "hot paths" - and they are not vibe-coding, they are doing an AI-assisted migration
@mauricio.szabo any source on that?
