In this Spanish‑language podcast, host Manuel Rubio interviews Kiko Fernández, an Erlang engineer at Ericsson. Kiko recounts his journey from early BASIC experiments and a love for Prolog, through a university education that introduced him to Haskell (initially disliked) and Clojure, to a PhD focused on functional languages and a subsequent role at Klarna where he used both Haskell and Erlang. He explains why Klarna hired him for Haskell and later taught him Erlang, describing practical differences between the two languages (I/O, concurrency, memory leaks, type safety). Kiko details his work at Ericsson’s OTP team, covering protocol maintenance, virtual‑machine responsibilities, and his involvement in the Erlang Workshop and the Erlang Ecosystem Foundation. He discusses new OTP 28 features such as Nominal Types for Dialyzer, binary joins, and incremental Dialyzer, and outlines ongoing research collaborations (set‑theoretic types, gradual typing) with Elixir, WhatsApp, and academic partners. The conversation also touches on community dynamics, the impact of Elixir and Glimpse, performance optimisation (JIT, micro‑optimisations), the feasibility of rewriting the VM in Rust, hiring trends, and the perceived stability of Erlang’s job market. The interview ends with encouragement for newcomers to engage with the Erlang community and foundation.
