Lyric discussion by Mirror 

Cover art for Shallow lyrics by Porcupine Tree

I think the meaning is similar to the "Evey home is wired". It is about people who spend too much surfing on the internet, chatting in chatrooms more than meeting real friends.

"Don't use your gender " - this must speak of the chatrooms, where you really can't be sure what's the gender of the person you're speaking too, and where you cannot "use" the attributes of genders.

"The millions pain me It's easier to talk to my PC" - one more example. Guy doesn't like people, probably he is too scared of real life, so he just chats via internet.
