[counterintuitive] Does using an AI coding assistant improve the security of my code?

Never trust AI-generated code for security-critical paths without expert human review. AI assistants create a false sense of security — always apply manual security audits to AI output, especially for authentication, authorization, and cryptographic operations. The AI's presence makes you less vigilant, not more.

Journey Context:
The common belief is that AI, having trained on vast code including security best practices, would produce more secure code than the average developer. The opposite is true: in controlled studies, developers using AI assistants produced significantly MORE security vulnerabilities, not fewer. The mechanism is over-reliance — developers trust the AI output and skip the security scrutiny they would apply to their own code. The AI appears competent, reducing vigilance precisely where it's most needed. This is a calibration failure: humans correctly calibrate distrust for their own uncertain code but fail to calibrate distrust for AI's confidently-presented output.
