You're just walking past a CS classroom when you catch a glimpse of the professor casually scribbling "P = NP ?" on the board. The entire class is frantically taking notes like it's some routine homework problem. Meanwhile, you're standing there knowing this is literally one of the seven Millennium Prize Problems with a $1 million bounty from the Clay Mathematics Institute. For context: P vs NP is one of the most important unsolved problems in computer science and mathematics. If P = NP, it would mean every problem whose solution can be quickly verified can also be quickly solved—which would revolutionize cryptography, optimization, and basically break the internet as we know it. Mathematicians have been wrestling with this for decades. So either this professor just solved the most significant problem in computational complexity theory during office hours, or those students are about to be very confused when they realize their "trivial proof" has a slight flaw.
