AI Writes 41% of Code. Only 29% of Devs Trust It. Review It Like a Senior Engineer
Key takeaways
  • Trust in AI-generated code has declined from 40% to 29% in one year, per Stack Overflow data.
  • AI code is 19% slower and 2.74x more likely to contain vulnerabilities, according to Veracode and METR.
  • The bottleneck in software development has shifted from code generation to verification and quality assurance.
  • Experts recommend a 10-point review checklist to mitigate risks in AI-assisted coding.
Full story

Recent data from Stack Overflow, METR, and Veracode reveals a growing skepticism toward AI-generated code among developers. Trust in AI-written code has dropped from 40% to 29% in just a year, while performance benchmarks show AI code is 19% slower than human-written alternatives. Worse, Veracode’s analysis found AI-generated code is 2.74 times more likely to contain vulnerabilities, highlighting a critical shift from code generation to verification as the primary bottleneck in software development.

The trend underscores a broader challenge: while AI tools like GitHub Copilot and others have accelerated coding, they’ve also introduced new risks. Developers are now advised to adopt rigorous review processes, with experts suggesting a 10-point checklist to catch flaws early. This shift reflects a maturing phase in AI-assisted development, where quality control and security take precedence over raw productivity gains.
