You think he's not using the tools correctly. I think you aren't doing your job responsibly. You must think he isn't trying very hard. I think you are not trying very hard...
That is the two sides of the argument. It could only be settled, in principle, if both sides were directly observing each other's work in real-time.
But, I've tried that, too. 20 years ago in a debate between dedicated testers and a group of Agilists who believed all testing should be automated. We worked together for a week on a project, and the last day broke down in chaos. Each side interpreted the events and evidence differently. To this day the same debate continues.
I am absolutely responsible for my work. That's why I spend so much time reading the code that I and others on my team write, and it's why I spend so much time building enormous test systems, and pulling deeply on the work of others. Thousands and thousands of hours go into work that the customer will never see, because I am responsible.
People's lives are literally at stake. If my systems screw up, people can die.
And I will continue to use AI to help get through all that. It doesn't make me any less responsible for the result.
