So, my question to you? Have you had bad experiences using AI?

1. You give the AI model a rather direct and constrained instruction (modify this code to also copy its output to this directory)....and the AI model will spontaneously decide that it needs to change 5 things in 5 different files to accomplish that, when in fact it was a rather simple change to the existing line of code. I find that Claude 3.5 does this the least....so when I'm in "surgical mode" I tend to rely on it.
2. Between runs, sometimes AI models will decide it wants a different architectural approach or code-style. So you write Function 1 and test / debug it and it works fine. Then when you come to write Function 2 the model chooses a completely different coding style and sort of a different "philosophical" approach to how it approaches the task. These can be very frustrating because maybe Function 1 it decided that the entire function should be self-contained, but when Function 2 is to be written, it then decides it needs to break up this task into 4 different sub-task....the result is that you get whats called "AI slop", that is a mishmash of different coding styles and approaches.
