As Information Era Technologies and their impacts on architecture change, their relationship calls for new or adapted concepts, where Buildings and Cities seamlessly intertwine with digital content and where the language of electronic connections tie in with the language of physical connections. Architecture cannot be just inhabited and rigid, but users and the environment should integrate with it. If computers were once the size of buildings, buildings are now becoming computers capable of performing on I/O Communication protocols or being programmed at molecular-material-nanoscale, or even operating on self-learning genetic algorithms. If the public space we inhabit today was basically constructed at the start of the Industrial Revolution, the Information Society is now bringing to bear new principles and technologies with which to rethink the functioning and structure of the streets, avenues, squares and infrastructure of the City.
