Why Erlang/OTP Still Matters in 2025

Hi folks! Ukrainian Erlanger is here :sign_of_the_horns:!

I’d like to share my recent talk at the TADSummit Online Conference, where I was kindly invited by Alan Quayle, Founder of TADHack and TADSummit.

In this session, I covered:

  • Why Erlang/OTP is still critically important in 2025
  • Its strengths and weaknesses
  • The industries where Erlang/OTP continues to shine (telecom, fintech, IoT, Voice AI)
  • Real-world examples of companies relying on Erlang today
  • The importance of our community and how we can keep it strong

Erlang/OTP, nearly 40 years old, still powers some of the most demanding real-time systems. Built for fault tolerance, massive concurrency, and hot code upgrades, it keeps mission-critical platforms running without downtime - from WhatsApp to fintech transaction engines.

:loudspeaker: I’d greatly appreciate your support - upvote, share the video, and leave any comments, questions, or your own Erlang stories.
Let’s remind the world together just how important Erlang/OTP is in 2025! :sign_of_the_horns:

I agree. Elixir seems to be very interesting to learn.
