The Impact of Discovering Life Beyond Earth by Susan Schneider

In the most likely scenario, if we ever encounter alien agents, it is likely that they will not be biological life forms, but rather super intelligent artificial intelligence. And so there are three main points to her argument. The first is what she calls the short window of observation. She makes an argument for this based on a previous accelerating rates of computation. At 20 60, after several small, but cumulatively profound alter ans, you are a post human. To quote philosopher nick bostrom, post humans are possible future beings whose basic capacities so radically exceed those of humans as to no longer unambiguously human by our current standards. That would be a prime example, i think.
