I’m maintaining a complete list of all TED talks on my wiki, with summaries for the best TED talks I discover.

As of now, TED had 787 talks. If a talk takes on the average 20 minutes to watch, assuming you don’t go look up or fact check anything that you learn, it would take you over 260 hours non-stop, or, if you had a job to watch TED talks 8 hours a day, with no breaks, it would take you over a month, even if you watched TED talks 8 hours a day on weekends as well.
