The concern is not exactly passion but what qualities it takes to maintain that passion. Is it realistic to expect a parent in their 40s have the same level of passion as a single engineer in their 20s? If not, passion can become a shorthand for age-discrimination. Does passion, as mentioned below, mean late nights fueled by monster drinks? If so, does it become a shorthand for 'people with disabilities need not apply'? ( I have a condition where "lack of sleep" means "more likely to have a seizure" ) Does passion preclude people with religious obligations? If the only people with passion are young health atheists with no family or time commitments then passion is discriminatory, and it valuable to have a discussion about what effect that has on our industry and our society.
