As far as I'm concerned, if you can hold it in your head, it's probably not worthy of being protected as a trade secret, at least if we're talking about something technical like software and not a KFC recipe. Downloading a bunch of data like the Uber guy is obviously theft, but being able to remember, in general terms, how some software program worked doesn't seem protectable to me: there's no way you could really re-implement it the same way just from memory unless you have some truly superhuman memory skills. Any modern codebase is huge, the product of dozens of people or more, and not something one person can hope to remember well enough to make a real copy.
