This discussion wasn’t created to ban AI or shame those who use it - far from it.
The goal is simple:
to prevent well-meaning developers from walking into traps they don’t yet see.Recently, while reviewing projects based on
L2jMobius, I noticed something concerning:
AI-generated code that "works" but will cripple server performance under real load.These aren’t theoretical issues - they’re
predictable disasters based on years of experience working with
multiple projects.
The Problem Isn’t AI - It’s Blind Trust- The code runs in testing but buckles under production traffic.
- It solves immediate problems while creating long-term technical debt.
- It ignores optimization patterns that experienced devs know by muscle memory.
A Warning, Not an AttackThis isn’t about
L2jMobius - it’s about
understanding systems deeply before modifying them.
When you:
- Copy AI code without grasping its impact on server architecture.
- Ignore thread safety, memory leaks and query optimization.
- Bypass established project conventions for "quick fixes".
- ...you’re not coding - you’re building a time bomb.
The Path Forward- Use AI as a brainstorming tool, not a production coder.
- Benchmark generated code under simulated load.
- Learn why existing systems work before "improving" them.
- Ask experienced devs to review AI suggestions.
AI is powerful - but
real-world systems demand real-world understanding.
Don’t learn this lesson the hard way when your servers crash at peak load.
