Why people recommend it

Each mark is one comment

  • Fault tolerance and graceful crashes

    “fault-tolerant languages such as Erlang/Elixir allow me to not worry about the billions of edge-cases”

    Comment from 26 May 2026 in “Use Boring Languages with LLMs”

    “letting things crash gracefully is so useful”

    Comment from 19 Nov 2025 in “Cloudflare outage on November 18, 2025 post mortem”

    “has a resilient environment with hot swapping”

    Comment from 3 Aug 2026 in “AI migrated legacy COBOL programs to Java, bugs included”
  • Safe, scalable concurrency

    “Erlang/Elixir will probably become more relevant as people move into massively parallel constraint solvers.”

  • Actor model fits problem spaces

    “the actor model implemented on top of a stable core (eg. Erlang/Elixir on BEAM) might be a natural fit”

What people warn about

Each mark is one comment

  • Multi-host clustering is immature

    “much like Erlang/Elixir the multi-host parallelization is not cleanly implemented... yet...”

    Comment from 17 Apr 2026 in “30 Years of HPC: many hardware advances, little adoption of new languages”

    “Clustering on OTP was certainly an area even seasoned gray beards tried to avoid.”
