The actual answer is to stop trying to treat literally every mechanic as if it were an inherent rule of physics or whatever. Smartlink in-universe is the same. Mechanically it has changed to fit an alteration of system.
This. It's all metagamey and handwavey to accommodate AR hacking of guns and eyes and whatnot. The Devs tried to make a system where combat hacking was a thing that was useful. They came really close, and honestly, it can be if the GM presumes the hacker has been looking around in AR before the shooting starts. "Realism" wasn't particularly a concern, fun and game balance came first.
If you presume that Shadowrun technology has advanced enough that modern day paradigms don't apply you can just treat the Matrix rules like magic. And given the amount of Otaku, Blood Magic, AI and other shenanigans that went into creating the Matrix 2.0 its as likely as not that there is some element of Magic in the Matrix. Hello, Technomancers?
Or you can use modern day real world analogies and bang your head against the rules to try and make them work.
