The carryover from computer science education to practice is so weak that you have to teach and persuade all over again. People leave school, get a job, and spend five years only using knowledge from their sophomore "Data Structures in C" class while struggling to catch up on all the critical stuff that their CS program taught them nothing about (SQL, source control, release management, etc.) Having misunderstood the purpose of undergraduate education, they believe this experience discredits everything they were taught in school, so they hold you to a higher threshold of proof if you're pitching ideas they heard in upper-level CS courses than if you're pitching ideas they've never heard before.
