Rather than asking "Do you trust this workbook?", why not ask "Do you want to import values or values and formulas?" then two buttons: "Import formulas and values" and "Import values only". Import values only should be the default
It's not like this is going to create fantastic AI.
Keep in mind there's been an amateur AI project for broodwar for almost 7 years now. Even after such a long learning period, the games are very primitive, and the AI's still couldn't pose a threat to even a beginner human player. Sometimes the games take hours. Trying to build strategy and decision making into an AI is incredibly complicated. There have been teams working at the SSCAIT for many years now, and the product is still fairly primitive.
So what CA did was instead write up a simpler AI that mimics strategy and decision making. We all know it's not great, but I'd be really skeptical that 3rd parties would magically create an AI that can think strategically.
