Virtual reality and manipulation

Virtual reality, backed by high computational power, makes possible subtle forms of manipulation that influences people but that they won't notice.

For instance, a political speech can be altered slightly for each person watching, making the speaker's face subtly resemble the viewer's face. This has been proven to make viewers, on the average, have a more favorable attitude toward the speaker.

The author proposes developing systems for detecting the use of this technique and other manipulation techniques.

I fear that nonfree software, combined with remote attestation, will be used to make it impossible to run the software to do this. It will be "unauthorized."
