It's not slower to do by hand. I race the AI all the time. I give it a simple task to write a small script that I need to complete a task that is blocking me... and the "thinking" thing spins and spins. So I often just fire up a code editor and write it myself, often before the AI is actually done after I have to cajole it through 10 iterations to get what I want. And when I race it, I get what I want every time, and often in the same or less time than it takes the AI (plus the time that I have to spend cajoling it).
