Okay... You misunderstood me... (Probably because I didn't elaborate one bit)
Obviously, our future lies in technology. Before long, we will do most of our shopping right at home. My theory is that software, games, you name it will all be part of one interface that is personal for.. well... each person. Its use will be as common as people use the bank, although you will not have to go anywere to use it.
As for steam, it is obviously not this. I believe steam is a good way to distribute games, although not steam in general... What I mean is.. Steam seems to be HL based, where a larger interface would be used for all games. Steam is not headed that way, obviously.
