Yes, I think it's clearly true. However, I don't think pg means people will be sitting at their desks to watch shows or movies. In many cases watching TV is a communal activity. People will just start getting media boxes or otherwise hooking their computers to the TV screen, as many geeks do today.

The reason why doing this isn't more common is because regular folk don't know where to get the content from. Bittorrent is far from mainstream.
