P vs np Memes

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.

Theoretical computer scientists really out here creating algorithms with time complexity that looks like someone smashed their keyboard while having a seizure—O(n 72649 lg 72 (n))—and then celebrating like they just won the lottery because "hey, at least it's polynomial time!" The P vs NP problem has these folks so desperate for wins that proving something is solvable in polynomial time (even if that polynomial makes the heat death of the universe look quick) is cause for celebration. Sure, your algorithm would take longer than the age of the universe to sort a deck of cards, but technically it's in P, so break out the champagne! It's like saying "I can walk to Mars" and when everyone looks at you skeptically, you add "well, it's theoretically possible!" Meanwhile, us practical programmers are over here optimizing O(n log n) to O(n) and actually shipping products.
