“No, [Ed Sheidt] doesn’t know the solution. I made that very clear that I didn’t want him to be able to decipher what’s going on … that I’d be modifying systems and developing my own, which would make it virtually impossible for him to decipher all of it.

The final part is obviously the, you know, the apex of the pyramid there.”
