Of course a bit anecdotal, but not once has either Gemini or ChatGPT suggested me anything with eval or shell=True in it for Python. Admittedly I only ask it for specific problems, "this is your input, write code that outputs that" kind of stuff.

I find it hard to believe that nearly 50% of AI generated python code contains such obvious vulnerabilities. Also, the training data should be full of warnings against eval/shell=True... Author should have added more citations.
