I have some degree of distrust of most of my applications. The "open trust" model usually ends up getting abused to the point where we have to lock it down...like early Windows, wide open for easy of administration, leading to things like the notorious "Blaster" worm, or the open architecture of the Internet, where we now have massive spam and DNS amplification attacks and all sorts of problems based on the notion of a trustworthy network. In general, everything in computing will keep going in the direction of "trust everything as little as possible for it to do its job" forever, I think, and probably has to.
