My version of Cory Doctorow's argument:

"Smartphones" are Turing Machines intended to be extensible with arbitrary "apps".

Once you grant app-hood, ALL bets are off - both for the good guys & the bad guys.

That's the nature of Turing Machines.

Sorry, Mr. Comey, but distinguishing 'good' from 'bad' apps is undecidable.

So either extensibility is out the window (the end of "smart" phones), or
Mr. Comey is out of luck.
