José Valim on feeding desire to learn, healthy Elixir ecosystem and the future of AI tooling
José Valim, creator of Elixir and founder of Dashbit, shares how he built one of the most loved programming languages by following curiosity over market trends.Key insights for devtool founders:- Build for yourself first - José's "selfish" approach of creating tools he actually wants to use led to authentic adoption and marketing. When you can explain genuine technical trade-offs instead of chasing trends, developers listen.- Decentralize early - Without Google/Apple-level resources, Elixir succeeded by empowering the community to own different domains (web, ML, embedded) rather than centralizing control.- Make pivotal technical bets - Targeting the battle-tested Erlang VM and enabling the Phoenix framework were key architectural decisions that paid off long-term.- Marketing = explaining trade-offs - Skip the sales pitch. Show developers exactly what they get and what they give up. José's rule: "If all we have is opinions, I prefer mine."- Enable ecosystem growth - Dashbit's consulting reveals adoption friction points, which feed back into language improvements and new open-source projects.Current focus: José is building Tidewave, exploring higher-level AI development tools that understand web frameworks, not just code.Companies using Elixir: Discord, Remote, Supabase, Fly.io, Apple, Toyota, BBC, PepsiCo, MozillaEvil Martians is the go-to agency for early-stage developer tools startups: https://evilmartians.com/devtoolsLinks:- Elixir: https://elixir-lang.org/- Tidewave: https://tidewave.ai/- Livebook: https://livebook.dev/- José Valim on X: https://x.com/josevalim- Evil Martians on X: https://x.com/evilmartians- Victoria Melnikova on X: https://x.com/vmelnikova_en

Adam Wenchel, CEO at Arthur AI, on building AI guardrails, the last mile problem, and coaching code bots
Adam Wenchel has been building AI infrastructure since before it was cool. As CEO and co-founder of Arthur AI, he's spent six years solving the "last mile problem" - getting AI from impressive demos to reliable production systems. In this conversation, we dive deep into why Adam open sources million-dollar tools, how his enterprise experience at Capital One shaped his approach to developer empathy, and his provocative prediction that we'll soon need fewer developers but better "code bot coaches."What we cover:- Why the gap between 90% demo accuracy and 99% production reliability is make-or-break for AI adoption- The strategic decision to open source Arthur Shield and Bench instead of keeping them proprietary- How working inside a 50,000-person company taught him to build better developer tools- Whether AI will eliminate junior developers (and why the answer isn't what you think)- The future of software development: from 50-person teams to 5 expert coaches- What makes the perfect developer tool (hint: simplicity + a sprinkle of cleverness)Adam's journey from acquiring a 5-person startup to Capital One to building Arthur offers rare insights into both enterprise AI deployment and the evolving landscape of developer productivity. If you're building AI tools, selling to enterprises, or wondering how to future-proof your development career, this conversation is packed with actionable wisdom.Links:- Website: https://www.arthur.ai/- GitHub: https://github.com/arthur-ai/arthur-engine- Adam Wenchel on X: https://x.com/apwenchel- Evil Martians on X: https://x.com/evilmartians- Victoria Melnikova on X: https://x.com/vmelnikova_en
