# AI now writes 97% of my code. Here's what I learned

**[swizec.com](https://daily.dev/sources/swizec)** · 7 min read · 175 upvotes · 34 comments

## Summary

A senior engineer at a near-billion-dollar company shares that AI (via Cursor) now writes 97% of their production code, including high-stakes systems like an invoicing platform. The key workflow: use Cursor background agents via Slack, don't watch them work, provide clear context and desired outcomes in prompts, then iterate with code review just like you would with a human engineer. The author dismisses elaborate prompt engineering tricks (Agents.md, plan mode, etc.) as distractions, arguing the fundamentals — speak clearly, give context, iterate — are what actually matter. A cautionary note: long-running agents that make early mistakes can produce thousands of lines of broken code, echoing the failures of waterfall development.

> Basically like the most basic principle of engineering, keep it simple. Simplicity is key

> Experimenting is the key as always. You will know how to guide agent properly only if you made 1000+ mistakes before same goes with learning.

> this is stupid... this is barely control... I think best way is to stay in IDE and peronaly review every shit AI writes so u see an issue in logic before it ate all ur context and limits, controllable AI dev is same as usual dev. But slack development........ Like playing russian rulette

> well, my AI agent WRITES my code, but I build my code and architecture... -_-
