Trusted Computing?

Trusted computing?  What the fuck?

Basically, everything will be encrypted, and only what is allowed to be run will be run, and only what is allowed to be read will be read.  The computer will be encrypted at every single segment.

EVERYTHING will be encrypted?  Doesn't that seem a bit like overkill?  I mean, encrypting people's diaries is all fine and good, but my 5th grade brother's book report too?

Can you say paranoia?

Why do we need this?

To protect the intellectual property of large companies. Why else?

If any part of it isn't encrypted, someone is going to crack or mod it. Even if it is encrypted, someone may still break it.

There are benefits to consumers, like making the lives of viruses even harder, but the real reason is IP.
