I'm reminded of a Nebula(?) Award winning short story about hive-rats interacting with nobility in the 'future'. The nobility is shrouded in apperance/voice/stim tech such that the AIs are more the person than anything. A princess is brought to the under-city by her father to a shop that can fix the princess' tech, as it is malfunctioning. The daughter of the shop owner tries to peer into the princess' life and psyche as the shop owner tries to fix the princess. The princess has implants that stimulate her face, voice, and body to say the right things at the right times, to move the right way, that changes her face via lightsheets to be most beautiful to the observer she is with, that causes her to say just the right thing at just the right time and be increbily witty. But the daughter of the shop owner tries to peer through the tech to see the woman behind the veil. She discovers that the person behind it all is nearly mute and has the intelligence of an infant. The tech had been installed before ego formation and the person behind it all didn't really exist. She discovers it is also true of the man that brought the princess down to them too. The entire nobility is essentially faking it.
I am SO sorry that I cannot find the link to the actual story. If anyone has the title or author, I would love to know!
