Ageism is just a dick move in general. It's gotten to the point where job candidates in their 30s and early 40s are dropping work history and education to appear as if they're in their 20s to potential employers - and even considering plastic surgery[1]. It's gotten completely out of control, but I'm quite glad to see more of my peers and younger colleagues taking a firm stance against it in any form.
As long as the work gets done, everything else is irrelevant. As long as the idea is successful, it doesn't matter the age of the person who surfaced it.
Stereotyping just gets your ass into legal trouble, and the easiest solution is to just not do it in the first place.
