Sometimes I tell the AI to change something, sometimes I just do it myself. Sometimes I start to do it and then the magic tab-complete guesses well enough that I can just tab through the rest of it.

Sometimes the magic tab-complete insists on something silly and repeatedly gets in the way.

Sometimes I tell the AI to do something, and then have to back out the whole thing and do it right myself. Sometimes it's only a little wrong, and I can accept the result and then tweak it a bit. Sometimes it's a little wrong in a way that's easy to tell it to fix.
