Expertise?
AI assistants were good at reminding humans of key details, "such as committing database changes, that might otherwise be overlooked."
Overlooking such basics says much more about the skills and attention capacity (or lack thereof) of the practitioner than it does about the utility of "AI". I never cease to be amazed by the shallowness of many of the questions on sites such as SO -- they lead me to believe that the software development profession is to a great extent populated with mere 'coders' who are novices at programming (two very different skills).
