I Took Harvard's Free Online Coding Classes To Better Catch AI's Errors - And They're Legit
ZDnet, Monday, December 29th, 2025
Harvard's free programming classes teach you how to think, debug, and adapt in an AI-driven world where knowing code matters more than ever.
ZDNET's key takeaways
- Free Harvard programming courses go far beyond basic tutorials.
- Learning to code still matters when AI writes software.
- The workload is heavy, but genuinely sharpens real skills.
In a time when AIs are writing code (and eating human coding jobs), you still need to learn to code. Why? If you want a program written, you can use an AI. But AI is wrong a lot - and confidently so. You'd better know how to code so you can confidently check your AI's work.
