Hi @lmaffeo!
Welcome to the forum! 
Congratulations for your book Designing Data Governance from the Ground Up! This is a very good topic.
You mentioned that there is an abundance of data without any quality control, and that low-quality data is often consumed. I think this is why Github Copilot sometimes generates code that requires more time to fix than to write from scratch. Copilot uses a vast amount of data available on Github, but not all of it is of good quality.
