The classic Python trade deal that no developer can refuse! Your beefy 16-core CPU thinking it's about to crush some serious computation, only to have Python's Global Interpreter Lock (GIL) say "that's cute" and proceed to use exactly ONE core. It's like buying a Ferrari and being told you can only use first gear. Sure, Python is easy to write and wonderfully readable, but when it comes to true parallelism, it's basically that friend who invites 15 people to dinner then makes them watch while they eat alone.
