    Concerns with his politics aside, I do think there's a truth to what he's talking about here, and that he is just spelling out the reality that developers are, or shortly will be, facing. For many this will be deeply uncomfortable to hear.

    It is notable that his perspective in this talk is very much from a developer-user side rather than someone who is responsible for the framework itself. That surprises me, and I suspect it is not a good omen for Rails.

    For all of this embrace of agentic development, there is nothing here on how they are adapting the framework for this new agentic development reality. Agents do currently work well with Rails, but there's nothing here pushing things forward as best as I can see.

    I know for my own projects I've largely moved to Elixir/Phoenix, for similar reasons to his use of Rust... I didn't want to have to learn it, but now I don't have to and I get to benefit from its strengths.

      I think a lot of people haven't actually watched his talk and don't understand what he is saying. If you watch the talk, he is not anti-rails. He is just very pro- agentic coding.

      What he was saying in his talk was that his customers (people using Hey for email and calendar) never really wanted hybrid web-native apps, they want native apps (like most people prefer on mobile). His business could never afford to have a dev team that built and supported six different native apps, so they always built using hybrid web-native stuff using Turbo Native.

      Now that his development team has access to agentic coding, they can build and maintain six mobile native apps. For his app, the back end part then becomes small and simple and they can reimplement it in rust to reduce server cost.

      His point wasn't that rust is better than ruby, or anything like that. His point was that agentic coding allows smaller teams to do bigger things. For most people building on rails, their customers don't need native mobile apps (I know mine don't) and for them Rails is a fantastic choice for agentic coding.

      Rails is so into agentic coding that they publish benchmarks of how effective different models are for building with rails:

      <a href="https:&#x2F;&#x2F;rubyonrails.org&#x2F;ai" rel="nofollow">https:&#x2F;&#x2F;rubyonrails.org&#x2F;ai

      TLDR: DHH isn&#x27;t anti-rails, he is pro-agentic coding. Rails is great with agentic coding. AI doesn&#x27;t mean layoffs, it means your teams can do much more than they could do before.

        &gt; If you watch the talk, he is not anti-rails.

        He explicitly said he still loves ruby as a language and thinks Rails is well suited for a future with AI coding.

        It&#x27;s interesting how this stuff gets spun on social media by people who don&#x27;t watch the content.

          It doesn&#x27;t matter if Rails is well suited for AI or not. Now, there&#x27;s less incentive and reasons to use it.

            When I started as rails dev in 2013, it was really the top solution for producing MVP fast. Now, I don’t think that’s the case and most of the incentives are gone if we are no longer writing code by hand
            1. mattbrewsbytes · · focus · HN ↗
              So what would you pick for producing an MVP web app fast that you also want to run in production, maintain, patch and scale that has a solid eco-system of pre-built libraries you can just plug in to solve problems?

                Java (Spring Boot, Quarkus).

              I prefer a Rails backend, especially in the agentic world.

              With an agent on a greenfield is when I’m most reliant on a framework for good standards and a clear architecture.

              This is one of the things Rails does really well.

            3. timr · · focus · HN ↗
              I strongly prefer Rails with agentic development. Rails comes with nearly everything you need to make a full-featured application, and that makes it easier and faster to use with agents.

              No other framework comes close, and telling me that I can have my agents cobble together this same baseline, badly, from a hodgepodge of new code and random libraries is not compelling.
