Ruby developer Julik Tarkhanov published an essay responding to DHH's RailsWorld keynote, igniting community debate.

DHH announced HEY was vibe-rewritten with AI and performed better, claiming he and Rails no longer matter — which the author reads as contempt for the Ruby ecosystem
The author isn't depressed about AI writing code (he accepts hand-typing every line is unsustainable), but about the disdain shown toward the Ruby community
His counterpoint: the rich and famous losing interest doesn't obligate everyone else — it frees up room; he sees a renaissance and calls this the "Weimar era of Ruby"
The piece captures senior engineers' anxiety and self-reinvention around tooling culture in the AI era
