Hey don't be the white person complaining about racism or the man complaining about sexism. If young people weren't getting a shot in the tech industry because of discrimination then I'd be a tad more sensitive to your protestations. But as it is, you're irrationally sticking your head in the sand. If you don't think that learn things and come to new insights that take years to develop then there's nothing I can say to convince you. But if you stick with it for a while, come back to me in 10 years and let's do a code review on what you wrote today and then we'll discuss if you still think I'm ageist for saying there are particular lessons learned through experience.
