#56 – The COBOL Crisis

You think your five-year-old React codebase is a legacy nightmare? Try sixty years. The entire global financial system—trillions of dollars, ATMs, credit card networks, and government mainframes—runs on a programming language older than the moon landing. And the only people who actually know how to read or fix it are rapidly retiring.

In this episode, we dive into the terrifying reality of the „COBOL Crisis.“ We explore the invisible, prehistoric infrastructure holding up the modern economy and the ticking time bomb of unmaintainable code. With an estimated 800 billion lines of COBOL still in daily use, banks and governments are in a desperate race against time. Do we train a new generation of 20-something developers in an ancient language, or do we trust artificial intelligence to blindly translate millions of lines of mission-critical banking code into Java?

In this episode, we unpack:

• The shocking scale of the problem: Why 43% of all banking systems still rely on a language invented in 1959.

• The „Silver Tsunami“: What happens when the only engineers who understand the core banking mainframe retire or pass away.

• The lucrative (but boring) world of COBOL consulting: Why some young developers are getting paid top dollar to maintain ancient code.

• AI to the rescue? The massive risks and rewards of using Large Language Models (like IBM’s watsonx) to automatically refactor mainframes.

The most critical software in the world is also the oldest. Tune in to find out how the tech industry is frantically trying to defuse the COBOL time bomb before the financial system crashes.
