Hi folks! Ukrainian Erlanger is here !

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.

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!
