The AI will write 80% of your code in 20% of the time.
And you’ll spend 80% of your time on the remaining 20%.
This isn’t a bug. It’s the entire point.
The boilerplate, the setup, the “we’ve seen this pattern before”—that’s the 80%. The AI crushes it. Five minutes instead of an hour. Copy, paste, ship.
But the last 20%? That’s where you live.
That’s the business logic that only exists in your context. The edge case your users will definitely hit. The architectural decision that will matter in six months.
The AI doesn’t know your technical debt. It doesn’t know why the previous developer made that weird choice. It doesn’t know that “simple and obvious” broke production last quarter.
You do.
Here’s what breaks: believing the AI should do 100%.
Here’s what works: using the AI to eliminate the 80% so you can think harder about the 20%.
The leverage isn’t “code faster.”
The leverage is “think deeper about what matters.”
The worst developers treat AI like Stack Overflow on steroids—grabbing answers without understanding questions.
The best developers treat AI like a junior pair programmer—fast at typing, needs direction, occasionally brilliant, frequently confident and wrong.
The AI writes. You decide.
80% of the bugs will come from blindly trusting the 80%.
80% of the value will come from obsessing over the 20%.
The question isn’t whether to use AI.
The question is: are you spending your time on the right 20%?
Because here’s the thing about leverage—it works both ways.
Use it wrong, and you ship faster in the wrong direction.
Use it right, and you finally have time to build what you couldn’t before.
The AI didn’t change what matters.
It just revealed what didn’t.
