Jaron Lanier, in his TEDxSF presentation, discussed the evolution of avatar s and their impact on the brain. He began by discussing how his team built the first virtual reality machines in the early 1980s, which had avatars embedded in simulations. He then talked about the development of mocap suits, which allowed for real-time avatar control, and the more accessible and affordable Kinect camera. Lanier highlighted the phenomenon of homunculus flexibility, where the brain adapts to new body shapes and can control new limbs. He suggested using this phenomenon for educational purposes and encouraged the audience to experience the joy of becoming an avatar. Lanier also discussed his latest project with Jeremy Bailenson, which involved manipulating a person's muscles to control virtual objects, and his disagreement with friend Kevin Brockman over the role of technology in society. Lanier advocated for a shift towards a human-centered approach to technology to address issues such as economic traps and a loss of privacy.

  • 00:00:00 In this section of the transcript, Jaron Lanier introduces his idea that digital information originated from an ancient Chinese instrument called a Sheng. He explains that this instrument has a long and rich history, both cultural and technological, and has influenced many other devices throughout history. He discusses the hydrolysis, which was a giant version of this instrument used in the Colosseum, as well as the player piano, which evolved from the organs thanks to the hydraulics that could sometimes be played semi-automatically. He concludes by mentioning that this gradual evolution of technology inspired people to create the programmable loom, which eventually led to the development of modern computers.
  • 00:05:00 This section of the TEDxSF talk by Jaron Lanier focuses on the history of avatars and how they have evolved over time. The speaker discusses how his team made the first virtual reality machines in the early 1980s, which had avatars embedded in simulations who could see each other in a social setting. However, the science of avatars and their cultural potential is still not well understood. Lanier explains that being in a 3D space where you see other people as different creatures is a unique experience. The availability of consumer gadgets like Kinect has changed the way avatars are controlled, making the avatar experience more accessible. He discusses the evolution of mocap suits, which were originally used for real-time avatar control, to the more simple and affordable Kinect camera. Lanier also talks about the challenges and bugs that he encountered while working with avatars, such as a bug in which his hand became a mile long. Despite these challenges, he describes the fascination and exploration of the limits of avatars that resulted from this experience.
  • 00:10:00 This section of the TEDxSF presentation discusses a phenomenon known as homunculus flexibility, which is the brain's ability to adapt to new body shapes and control new limbs. The nervous system has evolved over time to adapt to different body shapes, allowing it to learn to control strange or unusual avatars. This phenomenon can be seen in basketball players and other athletes who are able to solve complex athletic problems intuitively. This could be an exciting area of research, as it shows the possibility of unlocking new functionalities within the brain. The author suggests using this phenomenon for educational purposes, as it allows learners to become immersed in the subject matter and focus on it.
  • 00:15:00 In this section of the YouTube video, Jaron Lanier discusses his latest project with his research collaborator Jeremy Bailenson, which involves manipulating a person's muscles to control virtual objects. He also talks about his dear friend Kevin Brockman, with whom he disagrees profoundly on ideas surrounding technology, specifically the belief that technology should be designed for human purposes and not solely considered autonomous forces. Lanier argues that recent media designs, such as social networking and streaming services, have led to a dangerous economic trap and a loss of personal privacy. He advocates for a shift towards a human-centered approach to technology to address these issues.
  • 00:20:00 in this section, Jaron Lanier discusses the concept of "avatars" and their benefits for the brain. He encourages the audience to experience the joy of becoming an avatar, which, according to him, is a great gift for the brain that one can achieve within a few years.
