I watched a junior developer push a PR yesterday.
It was 400 lines of code.
It looked complex. It looked sophisticated.
It was also completely, utterly wrong.
When I asked him to explain the logic, he froze.
"ChatGPT wrote it," he mumbled.
This is the reality of software engineering right now.
The Power Saw Analogy
AI is a power saw.
If you give a power saw to a master carpenter, they will build a house in half the time.
If you give a power saw to a toddler, they will cut their arm off.
Right now, we are giving power saws to toddlers.
AI doesn't make you a better engineer. It just makes you write bad code faster.
Copy-Paste Without Context
Context is everything in engineering.
Why did we choose this database? Why is this component structured this way?
AI doesn't have the context of your 5-year-old legacy monolith.
It gives you a generic answer to a specific problem.
And when you copy-paste that generic answer, you introduce subtle, impossible-to-find bugs.
You aren't coding. You are just gluing black boxes together.
The Debt We Are Accumulating
Technical debt used to be created slowly.
Now, with AI, we are generating technical debt at lightspeed.
We are pushing code we don't understand.
Who is going to maintain this?
Who is going to debug it when it breaks in production?
The AI won't be there at 3 AM when the servers are on fire. You will be.
Fundamentals Still Matter
"I don't need to learn SQL, AI will write my queries."
Good luck when your query takes 45 seconds to run and takes down the entire database.
If you don't know how indexes work, AI can't save you.
If you don't understand memory management, AI can't save you.
Fundamentals aren't optional. They are the only thing that matters.
The Decline of Debugging
Debugging is an art.
It's the process of building a mental model of a system, forming a hypothesis, and testing it.
AI is destroying this art.
Instead of thinking, developers just paste the error trace into a chat window.
They are losing the muscle memory of problem-solving.
Seniority is About Judgment
What makes a senior engineer senior?
It's not typing speed.
It's judgment.
It's knowing what NOT to build.
It's knowing the trade-offs of a decision.
AI has zero judgment. It just outputs text.
Final Thought
AI is a tool, not a replacement for your brain.
If you use it to augment your skills, you will be unstoppable.
If you use it to replace your skills, you will be unemployable.
Don't let the machine do the thinking.
— Stay sharp.
