I Switched Between ChatGPT, GitHub Copilot, and Cursor Mid-Project — Here’s What Actually Happened

My 3-week experiment with AI pair programming revealed which tool actually saves time (and which one nearly broke my deadline).

Three weeks, three AI assistants, one chaotic project — the ultimate test of which AI pair programmer actually delivers on the productivity promises.

So my AI coding assistant crashed. Just completely died. Middle of a sprint, 72 hours before a client demo, half my React components broken.

I’m standing there at 2 AM staring at my laptop and I have this moment where I’m like… okay, I can either have a breakdown or I can do something incredibly stupid and turn this into an experiment.

The project was — okay, imagine if Figma and Discord had a baby. But like, a complicated baby that needs WebSocket connections and canvas rendering and state management that makes Redux look simple.

Why do I keep taking on projects like this? My therapist probably has thoughts.
