For coding I find LLMs legitimately revolutionary. I've tried letting DeepSeek & some local models like Qwen and Gemma loose on various projects to implement features and improvements and so far most of the time it didn't disappoint.
In the last couple of weeks I've been updating an old third party bot plugin for a game by prompting various behavior changes I'd like to see and it's a night & day difference to its original state. If I had done this by hand the time it took would've been multiple magnitudes longer, it'd have been more error-prone (especially since it's a C++ project written in classical C style, which is just UB galore) and I likely would've lost the enthusiasm to work on it by now.
Akin to screaming at the cashier for being unhappy about the supermarket's prices
