Thanks for an interesting post, great photos and a fascinating question.
I think the photo before the last conveys just your message: we see a maze of roads leading to the same circle - just like you said - the wisdom and the knowledge work in unity in the end, even if it looks like they are a bit different, just like the maze's road lead to the same whole circle.

I study medicine - and in my field you have to learn a waste body of knowledge, and then use your wisdom to implement it - so I really agree with your conclusion :)

And either way - if one of your friends was knowledgeable - he would know he has to shut down the engine, and if the other have wisdom - he should be smart enough to turn the car off too... so it's rather funny that after that hot talk - none of them implemented what he was after.
