Your code is better than AI code

A recent survey shows that AI generated code contains more bugs than code written by humans. This is somewhat surprising, given that AI code is probably generated from code

• that is better tested than the code you're just writing (supposing the surveys were done on fresh code)
  
• that it is generated from code from people who have more experience on the topic then you (supposing that a lot of the code is by experts and you are often on a learning path with a new technology). Again not sure if this was tested in the study.
  

Whatever the current state, AI will get better at this...
