I'm looking for the title of a short story I read on the internet somewhere a while ago.
It began with a girl living in the modern age and explores her life growing up over the next couple of decades, focusing on how she experiences new technological advances. For example, a pill is invented which uses nanobots to fix her aging brain and a chip is developed for implantation that essentially acts as Google-on-command in your head. At some point in her life, she talks to a scientist who is over-eager for all science's new developments and she instills a sense of prudence and caution in him that is a theme for the rest of the story. She is eventually made immortal, transcending human form or any form at all, and eventually acts as an ambassador to an alien species.
