My neighbor(He is 14 I think) pitched this to me and wanted advice since he was going try to participate in the Google science fair.

Him:"A robot that gives you medical advice. You just tell it your symptoms and voila! You've got your diagnosis. No doctor required."

Me: "How are you going to decide what disease the user has?"

Him:" I'm just going to write an if-else ladder statement. I've already got some of the data from this site called WebMD. It's amazing."

Me: "Go with something simple. What you're suggesting won't work out."

He told me I didn't have "Vision".
His ditched his project last week.
