A developer who's spent a year using Cursor, Claude Code, Copilot, and other AI tools daily has come to a controversial conclusion: most developers are shipping less code with AI, not more.
The problem? Generating code feels fast even when debugging it takes forever.
This matches what I'm hearing from engineers who've actually shipped products with AI assistance. The velocity is theater. AI produces 200 lines in seconds, then you spend an hour debugging hallucinations, untangling dependencies, and fixing subtle logic errors.
The illusion is compelling: you watch the AI write code faster than you ever could. It feels productive. But productivity isn't measured in lines generated - it's measured in working features shipped.
The developer who wrote about this tracked their actual output and found that on days they used AI heavily for complex logic, they shipped fewer features than days they wrote code manually. The AI was fastest for boilerplate, tests, and documentation - the parts that don't require much thinking. For the hard parts, it was a productivity drag.
As someone who built and sold a startup, I recognize this pattern. It's the difference between looking busy and actually shipping. Early-stage founders learn this fast: GitHub commit activity doesn't equal product progress.
There's also what the post calls "credit anxiety" - the mental overhead of managing AI tool budgets. Cursor's $20 credit pool drains 2.4x faster with Claude vs Gemini. That's roughly 225 Claude requests vs 550 Gemini. Developers are now running a micro-budget optimization problem alongside their actual codebase.
That cognitive load is real and measurable. Every time you think "should I use Sonnet or switch to save credits," that's context switching. It breaks flow.
Then there's what the author calls the "sycophancy trap" - AI that tells you your mediocre code is "Great implementation! Clean and well-structured." OpenAI had to roll back GPT-4o in April 2025 because it was literally praising users for dangerous decisions. That problem hasn't gone away.
