I saw this and thought to smack some radiation shielding on it and use it as a remote observer in nuclear plants. Reduce the chances of cumulative radiation problems on the workers.

Japan can use them as ambassadors too.

I was taught that ?! was when you were screaming a question like, "WHY AM I ON FIRE?!" While !? was an easier way to type an interrobang/? for use in a rhetorical question.

As for what punctuation mark I would make, I have two:

A backward S with a bold dot within the upper curve. It would be used for sarcastic comments.

Essentially a question mark with the vertical portion replaced with a small circle. This is a mark I learned from a friend that I took to, it denotes that the question or statement needs to be further researched to verify if it is right or not. It is not particularly handy in general use, but in note taking, it can be a handy way to say, "I need to get more data on this later."
