Open thread, Feb. 9 - Feb. 15, 2015

If it's worth saying, but not worth its own post (even in Discussion), then it goes here.

Notes for future OT posters:

1. Please add the 'open_thread' tag.

2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)

3. Open Threads should be posted in Discussion, and not Main.

4. Open Threads should start on Monday, and end on Sunday.

And the complementary question: What should we not do because it will likely be superfluous in the future?

Examples:

Learning all kinds of facts (this is already mostly the case thanks to search engines)
Learning any languagse (except possibly a mainstream language like English if you speak only an endangered language)
Tagging images on your hard-drive
Entring data in a highly structured form for 'easy' retrieval (like person data as firs/last name, age, occupation...)
