No need to be that harsh. It is good enough to recall a fact,a software engineer is a producer but a product manager is an overhead.

I think he needs to go back to school. He even doesn't know what the job description of a software engineer is. He says:"Software engineers write code ..."

Moreover, he contradicts himself. He compares himself with Steve Jobs. He says:"Don’t bother with the details." But, Jobs said:"Details matter. It's worth waiting to get it right."
