Is it possible, in SR, to record memories? It is possible to record emotions, that is what Simsense is right? With the right cybereyes and ears you can record sight and sounds, but can you record memories, transfer to a external device for recall later or transfer them to someone else?
If that is possible would it not be possible to hack those memories and change them? If you could do that couldn't you hack someone and make them your slave?
Memories are complex things that we really don't understand today.... They are formed from all sorts of physical stimuli and personal persepective, moral centering, past experiences, and a host of other things. While you could use a heavily cybered individual and record all his sights/sounds/feelings... the end result for someone else viewing those recording would not necessarily have the same 'memory' of the evernts as the original person. Sure they would know what happened, can maybe give a detailed report on the events, but close examination would show small variances in details. This is because of different 'background' emotive stimuli.
IE: the original person might not bat an eye at bloodshed and gore, yet remembers seeing a pretty girl fleeing the scene, or his hatred of orks gives him a certian level of 'comfort/pleasure' as he watches an ork bleed out.
Then the viewer watches the events, and remembers the event, he is conflicted, he has no hatred of orks, but 'remembers' the pleasure of the ork dying. He has no explossure to violence so in his perpective, his memory focuses on the death and gore, and conflicts with his passive emotions to the events. and since he is not interested in women, this more a couriosity why he remembers her at all.
Technomancers seem to have the ability to download their memories like James says, but it is kinda unclear what anyone else would get out of them, or if they could even be viewed by someone else. Makes for interesting fiction that shoudl be explored (HINT HINT writers!
)
Another sick use of 'memory manipulation" are Bunraku parlours that install heavy cyberware into their workers that override their ture personalities and "impose' those of famous celebrities onto them. It is memtioned that they rarely remember their actions while serving as meat puppets and they have a high instance of mental burnout and psycosis.
As to actually "hacking' the wetware (living) part of someone's brain and controlling them through technological means, there is no data about it happening in SR that I am aware of. there has been no cases of, say, a TM hacking into someone's head in a matter of minutes and then controlling them like a drone. (this was one of the fears used to fuel the flames of hatred against TMs) So I would have to say "nope". There seems to be no way to hack a brain and conrtol someone, only subvert them.
IE: brainwashing through "mundane" means (VR overloading, chemical useage, and lots of other nasty tie-you-to-a-chair-and-submit-you-to-300-hours-of-barney-the-dinosaur-videos freaky things.)
