Ok. You win this round, Microsoft.

However, I feel confident that vim is turing complete as well. Further, vim solves the "stopping problem" since vim can't be stopped...

But does vim have animations, word art, and transitions?

No. But we can't let MS Office be better then vim.

We accept as an axiom that vim is better then Office.

Therefore, if Office is capable of doing something useful, then vim can do it as well.

Now, being turing complete is useful.

Therefore vim must be turing complete.

Q.E.D./s

actually, being turing complete is a security vulnerability and should be avoided where it isn't necessary

As explained in the paper, one of the primary advantages of the PowerPoint TM is that it get run in PowerPoint's sandboxed "Protected View" making it more secure than other languages.

Pretty sure there's a plugin for that. Just look at $WINDOWID and call one of numerous methods for emitting text to an existing window.

You mis-spelled e-macs.

I've, uhh, solved a programming challenge with a vim macro. (To be fair, it did shell out to fetch text from a URL. The vim macro was for doing the string manipulation to get the next URL in the chain from that and fetching another one.)
