Exocomputing in the Year 2304: A Survey of Confirmed Alien Information TechnologiesYou should register right now so you can see this talk live.
As more alien civilizations have been encountered in recent decades, a variety of exotic information technology strategies have come to light. It has often been difficult to analyze these technologies, as alien cognitive and social factors must be taken into account, and these are in themselves challenging to interpret. It is now becoming possible to present an overview of a variety of alien information technologies and to glean insights into how they might inform the future of human IT as well as what might be expected from future alien encounters.
