You've got Claude/GPT running in your IDE. You ask it to write a function. It spits out 47 lines of code. You hit paste. Boom—it's in your codebase.
Here's the thing: if you don't understand what that code does, you just shipped a problem.
I'm not saying don't use AI tools. They're fast and genuinely useful. But there's a difference between using AI as a thought partner and outsourcing your brain.
The Real Problem
Three months from now, that function breaks. Maybe it's edge case handling. Maybe it's a subtle bug with async behavior. Maybe it was never actually correct—it just worked for your specific test case.
When you have to debug it at 2 AM, you're going to wish you understood what it does.
The developers who are thriving with AI tools aren't the ones who use them blindly. They're the ones who treat AI output like code review—skeptical, hands-on, and ready to challenge it.
What Actually Works
1. Generate, then rewrite it yourself
Don't just accept the AI's structure. Ask yourself: would I write this differently? Is there a simpler way? What edge cases is this missing?
I asked Claude to write a date parser recently. It gave me something solid, but then I rewrote 30% of it because I realized I could handle timezone logic differently. The AI solution was correct; my version was just more aligned with how my brain works.
2. Understand every function before committing
This isn't paranoia. Read the code. Trace through it. Ask "why did it do that?" about the parts that aren't obvious. If you can't explain it, you don't understand it.
Real talk: if it takes 5 minutes to understand an AI-generated function, that's a good sign. If it takes 30 minutes, something's probably overcomplicated.
3. Test aggressively
AI tools are good at the happy path. They're not mind-readers about your specific data, your production constraints, or your weird edge cases.
Write tests. Especially the awkward ones. Empty arrays. Null values. Huge datasets. Malformed input. Make the code prove it works.
4. Mix AI with your own solutions
Don't let AI be your only approach to a problem. Sometimes I'll ask an AI tool to solve something, then I'll also solve it my way, then compare. I learn way more that way than just taking what it gives me.
The Bigger Picture
This is about maintaining the skill that matters: problem-solving. AI is amazing at generating syntax. It's terrible at understanding your actual problem if you're not clear about it.
When you engage with AI output—questioning it, testing it, refining it—you're actually building better instincts about what good code looks like. You're learning.
When you just paste and move on, you're getting lazier at the exact skill that keeps you valuable.
One More Thing
The developers who are getting pushed out aren't the ones who use AI. They're the ones who outsourced thinking. The ones who stopped asking questions.
Use your tools. But be present. Code with intention. Understand what you ship.
That's how you stay sharp.
