Yeah I'm really trying to think. It's tough to think of something where a computer can't just process and then have some output that changes physical matter after or even during the process. So it would need to be something that requires the object that is doing the calculation to change while calculating?

I'm trying to view it in a good way.

Radiation-resistant computation comes to mind.

If they make their fluid inert (what is a relative characteristic), there are probably several application in chemistry.

What possible applications?

Meaning, what other possible real-world uses can be conceived of?
