i think this is the most misleading thing about cyberpunk and hollywood hacking tropes... that there is a cyberspace that actually exists in some allegorical way and that a user's avatar can actually "travel" from point to point looking upon and travel to floating pyramids of information. that analogy is totally wrong.
the far more accurate analogy is simply making telephone calls. if you are anywhere at all, you are right smack dab, ass down in chair in front of your computer. and your computer itself doesn't ever travel anywhere. all it is doing is sending and receiving messages. sure, you're getting messages from different nodes but that's just like receiving lots of phone calls from different people.
you can surreptitiously send messages that cause unexpected behavior or make a call under an assumed identity... but ultimately, all hacking is about sending and receiving messages...
and it's amusing how far hollywood and narrative fiction has to go to make that seem dramatically interesting.
