I can't wait until we have fully realistic virtual reality.
A la shadowrun? XD
Keep in mind that there can be ALOT of problems with such too... as shadowrun also shows >.>
Alright so I'm using a fantasy/sci-fi series to explain, but it does give a good idea of alot of the issues that may be faced, so a little backstory for those unfamiliar.
In shadowrun, the internet ends up crashing due to several reasons, which aren't really important. Whot happens though, is they update the material infrastructure to be dedicated purely for online interfacing, much, much faster, and so on. This new internet is dubbed the matrix (long before the matrix movies were out, by about 20 years )
The matrix allows people to browse via an avatar; information is stored in a 3D space with representations of everything. So for example, a nordic based company may store their sensitive information in a 'castle', or dungeon keep, with their anti-virus software appearing as mythological figures, such as Fenrir.
If one were to hack into the site, then the programmer would create tools which are fitting for their avatar usually; to break the ICE - Intrusion Countermeasures, yeur avatar may end up swinging a sword at these fenris wolves, but the programming going on in the background is essentially that the antivirus software is attempting to delete, remove, or isolate the attacking program, whereas the attacking program is adapting and changing to meet the challenge presented to it. So it may LOOK like a sword fight against a mythological creature, it's just program code adapting to compete with each other.
In a fully immersive virtual reality world, that's whot yeu could probably expect, honestly.
Now... there's problems with this. Particularly high end expensive and powerful ICE could kill the user or leave them braindead if they get in a fight with it. People often have implants, such as a HUD built right into their brain so they can see stuff like the time on command. Often these implants are connected to the matrix in some way shape or form, and this can lead to people actually hacking into yeur brain.
There's issues with viruses, and then there's the 'drug' matter... when yeur brain becomes capable of accepting whot's essentially USB flash drives to just slot right into the brain to give yeu information... how long do yeu think it'll be before someone comes up with a way to slot in 'happy' thoughts and essentially program yeur brain to be 'high'?
There's all sorts of nasty things that can go wrong, and the last thing yeu want is to have yeur brain get a computer virus, because "rebooting" may not be an option ;_;
