Multiplexing vs Multitasking

Research with the population at large to date suggests that our ability to multitask is not as great as we think it is. Starner replied that he multiplexes rather than multitasks. Multiplexing means doing tasks that reinforce each other. For him, taking notes and having conversations are tasks that parallel and enrich each other. They are multiplexed. On the other hand, he doesn’t try to manage email during a conversation or while walking down the street. That would be multitasking. “If the wearable task is directly related to the conversation, the user’s attention is not ‘split’ and multiplexing can be pretty effective.”

Some combinations of tasks can be multiplexed effectively. The question is which ones.

The Satisfaction Paradox

a future where amazon and others sell the recommendations as a service but the actuals goods are free.

While it may be a long while before every adult is sharing art or innovations on a global scale, we can already see the abundance of good stuff piling up. Netflix has more great movies a click away — after I filter out the dross — than I can watch in my lifetime. What do I watch next? Spotify and other music streaming services will have more fantastic, I-am-in-heaven music available everywhere all the time than I can ever listen to. What do I listen to next? Google will have every book ever published only 125ms away, and collaborative filtering, friends recommendations and a better Amazon engine, will narrow down those stacks to the best 10K books for me. So what do I read next?

I believe that answering this question is what outfits like Amazon will be selling in the future. For the price of a subscription you will subscribe to Amazon and have access to all the books in the world at a set price. (An individual book you want to read will be as if it was free, because it won’t cost you extra.) The same will be true of movies (Netflix), or music (iTunes or Spotify or Rhapsody.) You won’t be purchasing individual works.
