'Going online' in the interstellar network is vastly different from being in cyber space.
In cyber space, you feel the crowdedness of 'people sea,' with network viruses, personality fragments, rogue programs, emotion plugins, natural AIs, and so on. These rising and falling network monsters demand even cyber hackers to be cautious. One slip-up and a successful virus download means your physical body in reality gets overtaken.
By then, you can only pay to hire someone for physical cleansing.
But in the interstellar network, the first feeling of virtual gravity is that it's vast, empty, and the network signal—slow!
Generating a page with a virtual program is like using a free VPN. The speed is so slow it gives him a headache.
The speed of light signals is naturally at light-speed, while the electrical and chemical signals generated by the human brain certainly can't match light-speed. Thus, the network access chamber exists.
