I thought it was about the isolation of this digital age - "curled up with machines" meaning that he is obsessed with his computer/electronics rather than people. And maybe he's using the Internet to escape from harsh realities, choosing not to find out or deal with what's really wrong with him - "what's really haunting you."
The "your heart only beats 1's and 0's" refers to the binary system, which is part of most computers. The 1's and 0's are often associated with the on/off function - "switch you on my friend." A very haunting song that reminds me of something else, though I can't quite think of it yet. Extremely sad.
