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 presentation, I discussed:

  • Why Erlang/OTP is more important than ever in 2025
  • Key strengths and weaknesses
  • Industries where Erlang/OTP continues to shine - telecom, fintech, IoT, Voice AI
  • Examples of companies still relying on Erlang because of its unique capabilities
  • Thoughts on the Erlang community and how we can keep it strong

Erlang/OTP, now almost 40 years old, still powers some of the most demanding real-time systems. With built-in fault tolerance, massive concurrency, and hot code upgrades, it remains unmatched for building reliable, distributed applications.

:loudspeaker: I’d be very happy if you could like, share, and comment on the video - whether it’s feedback, questions, or your own experiences. Let’s work together to remind the world just how important Erlang/OTP is in 2025! :sign_of_the_horns:
