I genuinely don't understand how is everyone having such a bad experience. Granted, I hardly chat or use it for research, but every task I've given to codex has been successfully fulfilled. Two last ones were optimizing a web page that drew entire world map with lots of details (actually blew my mind, it was like 95% faster) and fixing a mod in a videogame. I've created custom app for a radio station I loved but didn't have basic features like previous songs, I've created an entire web game in 3 hours, I've created mods for games, etc., all without a fail.

This thing has saved me lots of headache, yes everyone here claims it's so bad and useless and a complete bubble, meanwhile in the last year it has basically only started working and only now can businesses start adapting it (I'm sure early adaptors were not happy)

EDIT: you just know this comment will receive silent grunts and hardly any real counter-arguments because I'm right.
