The Muse is a AI companion that assists its owner on every day basis. Often it does so from early childhood and knows it's master very well. It resides in master's mesh inserts and to be able to serve master well it has to store a wealth of information there.
So: why retort to transhuman's psychosurgery, torture or VR fork interrogation if theirs Muse has full access to their senses and registers it as part of its duty? Isn't it easier to hack the Muse than to crack transhuman mind?
But is Muse's knowledge of its master and their proceedings really complete? I expect that Muse can be asked to skip recording some sensory input, even delete already recorded one from its own database... But what if it owes higher allegiance to authorities (like Titanian Muses could) or has already been hacked and some kind of wiretapping has been placed? Or does it simply log deletion request for purposes of maintaining database integrity?
How much can be learned from interrogating or wiretapping Muse and how is it done?
