Tools: Ai Wrote 1000 Lines Of Code. I Found The Bug In 3 Lines. 2026

We used to tell computers how to do things. Now, we tell AI what we want.

But here’s the catch 👇 AI can write 1,000 lines of code in seconds, but it doesn’t understand:

So who’s going to catch the bugs? Who’s going to spot the security hole in line 743?

Let’s talk about the new superpower developers need in 2026: 👉 Reading AI-generated code like a detective.

“Build me a dashboard where users can log in, see their analytics, and export reports as PDF.”

In 2026, the most valuable developers aren’t the ones who write the most code.

They’re the ones who can spot the mistakes in AI-generated code before it hits production.

Does this code actually solve the business problem?

A startup used AI to build their entire payment system.

The AI wrote a floating-point calculation that worked for small numbers.
