What should I watch out for with AI in IT & software development?
Source code is trade secret and intellectual property. Check whether AI coding assistants store your code or use it for model training (an opt-out or business plan is required). Use on-premises or privacy-compliant variants for sensitive projects. AI-generated code sometimes contains security vulnerabilities or errors, so always have a developer review it, especially production code.
