If you compare mommy and her birthday cake with Teamspeak 5, it's as if on the morning of the birthday party mommy says: "kid, this year I will bake you and your guests a brand new cake." Then she goes to download the new recipe from some recipe database and is going to study what ingredients might be required. Then she goes out to buy them, realizing that not everything is available from stores nearby. When she comes back with all the ingredients, it's afternoon and the party is about to begin and the first guests arrive. While the party starts with hungry guests, she tries to work out the recipe and create the cake. It's complicated and requires many steps of preparation. It's not yet in the oven when the party is over and the guests start to leave. The next day, the first version is half baked, and the second one is burnt. The next one is too sweet, because the recipe dictates too much sugar. But some day later she might have figured out how the recipe is to be interpreted. Perhaps next birthday.
