I actually don't. All that is required is a Comlink. You can go dark for EVERYTHING ELSE, even in SR5.
First, sorry if that came across a little sharper than I intended.What I meant to infer was to stop at that point in the paragraph. That AR is interactive, not just a "I look at the AR". Here is a paradigm I think might help give an example why AR is not just a "read-only" thing.
1. Install Firefox. Add the "No Script" ad-on.
2. Sure the web. Notice how many sites seem broken.
3. Disable "No Script".
4. Surf the web and notice how everything looks now.
Scripts are being pushed to your browser, and by extension your PC, to give the feature rich web environment. Those same scripts put you at risk. AR is like that. You either turn it on, or you don't. If its off, you miss lots of stuff. If its only, you get the feature rich AR, but you are not vulnerable.
If you turn off AR, you miss A LOT OF STUFF. You can't just "go dark". If you do, you disconnect from society.
