A spicy Reddit drama where an 18-year-old dev fails a quiz because his teacher claims Facebook uses IRC, React is garbage, and only PHP is valid. Who is right?

What's up, fellow code monkeys. Just scrolling through Reddit today and stumbled upon a drama that made my brain hurt and my sides split. We've got an 18-year-old kid getting absolutely obliterated by his "stuck-in-the-90s" teacher just for... thinking like a modern dev. The takeaway from this isn't just about tech stacks; it's a harsh survival lesson for all you junior devs out there.
Here is the TL;DR for those who hate reading. Our OP (an 18-year-old self-taught dev since he was 14) is taking a Network Protocols class in high school. The teacher drops a 5-minute pop quiz: "How to create a chat app?" No other context.
Since OP had skipped the previous class, he pulled from his real-world arsenal: WebSockets, TCP, HTTP polling, Socket.io. He wrote it all down in 5 minutes.
The result? Failed. 2/5. But the absolute mad reasoning behind the grade is what broke the internet:
To add the cherry on top, this guy is the school's sysadmin who manages their cloud vps. OP was so salty that he dropped the link to the school's website (built by this "expert") for the Reddit hivemind to roast.
With nearly a thousand upvotes, the comments section turned into a literal warzone. People split into three distinct camps:
Camp 1: Roasting the dinosaur teacher The immediate reaction was brutal. "Saying CSS slows down a website tells me everything I need to know about this 'expert'." Even hardcore PHP devs chimed in: "I love PHP, but this guy is delusional. Bro is stuck in 2005."
Camp 2: The Reality Check A senior dev named Kynaras dropped a massive reality bomb on OP: Hold your horses, kid! This is a high school class. You literally admitted you SKIPPED the last class. A 5-minute quiz is designed to test the material taught in the previous lesson. If the teacher taught IRC yesterday, and you show up today vomiting WebSockets and Socket.io without answering the actual prompt, you deserve a zero. Ignoring requirements and publicly shaming your teacher's work online reeks of teenage angst.
Camp 3: The Pragmatic Approach The veterans in the sub just sighed and offered the golden rule of employment: Just give the guy what he wants, pass the class, and forget about him.
Looking at this mess, both sides messed up. The teacher is a dinosaur with out-of-date knowledge who loves to flex his authority. The kid is too cocky, thinking his cutting-edge knowledge makes him immune to instructions.
Welcome to the real world, kid. Soon you'll meet clients, bosses, and Product Managers who are ten times more technically illiterate than this teacher. You might propose an elegant, perfectly optimized solution, but if the boss says, "I want to use this legacy tool because I'm used to it," you swallow your pride and write the code.
Adaptability is your ultimate survival skill as a dev. Your job is to solve the problem within the given constraints—even if those constraints are incredibly stupid. Having a massive ego and always needing to be "technically right" won't pay your bills. In school, the teacher holds your grades; at work, the boss holds your paycheck. Deliver what's asked, secure the bag, and save your fancy tech stack for your weekend side projects.
