Nano-robots. In less than 50 years, these tiny machines could change our world to a place where “the concept of one mind, one body will be obsolete.” Humans will live in a virtual world with control over aging, health and physical characteristics. Scientific evidence shows that ‘The Singularity’ has already begun: the point at which technology and its creator are no longer mutually exclusive. Bay Area filmmaker Doug Wolens presents his new film on Sunday, Nov. 24, at Rafael Film Center. 1118 Fourth St., San Rafael. 7pm. $10.75. 415.454.1222.
