AI Agents Are Great at 80% of Our Code. The Other 20% Is Why We Still Need Seniors.

We let AI agents loose on a payment platform. They crushed the boring stuff. Then they silently broke the stuff that matters.

A survey came out last week. 54% of all code is now AI-generated. Up from 28% last year.

I read that number and thought: yeah, that tracks. We're probably in that range too.

But here's the thing nobody's asking — which 54%?

Not all code carries equal weight. A CRUD endpoint for fetching merchant details? Low risk. The webhook handler that transitions a payment from pending to complete? That's someone's rent. Someone's payroll. Get that wrong and money moves where it shouldn't, or worse, money doesn't move at all.
