If a society in Science Fiction isn't either following Technology Levels or magic, then you can rest assured that they're making use of organic technology. Cars, planes, phones, computers, buildings, spaceships, weapons (including artillery and war vehicles) and everything else required for a proper sci-fi story will be provided in the form of something that is warm, moist, skooshy and drips goo everywhere. Often, this will go so far as to include a convenient thought-based interface.
