Lol, no. The person who can bullshit the best keeps the job. Valuable people have the self-destructive tendency of delivering honest bad news.
I say this as someone who has both been a valuable employee and managed fairly large departments. And who grew up long before LLMs existed. An important thing to remember is that hiring and firing decisions are generally above the team lead's pay grade, meaning that a bullshitter just has to network upwards.
Sure, cheating at uni will cripple the kids, but only the frontline employees, not those who tip straight into management.
