FORTUNE — If you want to know what Tim Cook meant last week at All Things Digital when he said Apple (AAPL) was going to “double down” on secrecy, you only have to spend some time listening to the six appearances his predecessor made at the same conference between 2003 and 2010, free podcasts of which have been made available on iTunes here.
Steve Jobs used to joke that Apple was a ship that leaked from the top, and with the benefit of hindsight you can find plenty of instances in these podcasts.
Developer Ole Bergman spotted this one in D3, in which an animated Jobs — two years before the launch of the iPhone and five years before the iPad — reveals one of the key elements of what Jobs later dubbed the post-PC era: An operating system in which the file structure disappears. It comes at the 37:40 point in the podcast, which you can get here, during a demo of Spotlight. Bergman’s transcript (emphases his):
You won’t see the preternaturally disciplined Cook doing something like that in a public forum.
