Back In Our Time

Grandma's not senile—she's just a Python threading expert who's lived long enough to remember the GIL wars. The Global Interpreter Lock (GIL) is Python's infamous party pooper that forces your fancy multi-threaded code to basically take turns on the CPU like kids waiting for the ice cream truck. While junior devs are busy writing "async" everywhere thinking they're parallel programming wizards, Grandma here remembers the brutal truth: your 32-core machine is essentially a very expensive single-core processor when running Python threads. Maybe we should listen to her wisdom instead of wheeling her back to bed—she probably wrote COBOL that's still running the banking system you used this morning.
