The agent finishes another PR while I'm halfway through reading the last one. Five minutes of build, twenty minutes of read. The math used to point the other way.
I'm the only reviewer on Phora. There's no team to absorb the asymmetry, so I feel it directly. Most days I generate more code than I can honestly look at.
Everyone calls this a tooling problem. From where I'm standing, it looks like a discipline one.
The numbers don't add up
By Gartner's count, 60% of code will be AI-generated or co-created by the end of 2026. Output per engineer is up roughly 60% year over year. A CodeRabbit study found AI-written code surfaces about 1.7× more issues than human-written code. In Anthropic's coding report, developer trust in AI accuracy dropped from 40% to 29% in twelve months.
Set those four numbers next to each other. More code, more bugs, less trusted. The productivity gain is real on one axis and an unpaid loan on every other.
More tools don't close the gap
George Witt's piece in CodeToDeploy this winter argued review isn't becoming obsolete; it's becoming the part of the job that actually compounds. I agree on direction, less on remedy. The industry's current answer is "AI reviews AI": automated tools that triage the flood before a human sees it.
That helps. It doesn't fix the asymmetry. The reviewer is still the person whose name is on the merge. Whose judgment carries the architectural cost. Whose mental model has to hold the system. You can shorten the time per review. You can't hand off the responsibility.
A team shipping ten PRs and honestly reading three is a team living on the next quarter's bug budget.
Generate less
The unfashionable answer keeps pulling me back: cap generation at review capacity. If I can honestly review three PRs today, I generate three. The agent doesn't decide that; I do.
This sounds soft. It isn't. Every line I ship without reading is a line I'll review later, more expensively, after it has broken something. Speed without review is deferred review.
The bottleneck was always review. AI just made it impossible to hide.
There's always a next level.
If you like what you see (whether you're building a product or a team) I'd love to hear about it.
