Watching the talk and reading the comments, the comment that struck me was a reasonably factual statement that "History" is becoming extremely dense. The libraries of the world, the manuscripts et al even film up till the creation of Youtube pale in comparison for the shear volume of data available to the modern or future historian that can access it, enabling a synthesis of vast quantities of information and perspectives regarding a specific moment in time.
Apart from that for one's own future self might appreciate an application like OpenPaths (it gets a mention about half way in). Since we already give up our movements to companies like Apple or the various developers whose apps we use, it is nice to find an app that tracks movements and displays them over time, visually. Ape may have a playback running along with other media collected digitally embedded in Ape's tombstone.
OpenPaths App for iPhone and Android devices
"Using our mobile apps you can track your location, visualize where you've been, and upload your data to the OpenPaths website. You can then download your data from the website in a variety of friendly formats, including KML, JSON, and CSV. The OpenPaths API enables you to integrate your own software with the platform, and you can import data from location-based services like Foursquare."
