Matrix multiplication Memes

Remember when you thought matrix multiplication was the coolest thing ever? Yeah, that innocent enthusiasm lasted about as long as your first sprint planning meeting. You were out there thinking "wow, I can multiply matrices!" while AI was already plotting to automate your entire existence. The real kicker? That same math you thought was just academic flex is now powering the neural networks that are literally coming for everyone's job. Plot twist: you weren't learning cool math tricks—you were training your own replacement. The irony is chef's kiss.

Google's AI Overview just confidently explained that matrix multiplication "is not a problem in P" (polynomial time), which is... hilariously wrong. Matrix multiplication is literally IN the P complexity class because it can be solved in polynomial time. The AI confused "not being in P" with "not being solvable in optimal polynomial time for all cases" or something equally nonsensical. This is like saying "driving to work is not a problem you can solve by driving" – technically uses the right words, but the logic is completely backwards. The AI hallucinated its way through computational complexity theory and served it up with the confidence of a junior dev who just discovered Big O notation yesterday. And this, folks, is why you don't trust AI to teach you computer science fundamentals. It'll gaslight you into thinking basic polynomial-time operations are unsolvable mysteries while sounding incredibly authoritative about it.
