It’d be nice if our tools promoted disciplined, focused use instead of combatting focus. The internet is a huge component in this.
I value, quite a lot, all the different forms of interaction that aren't mediated through a screen. I worry that in a world of omnipresent entertainment and connection to the mega-mind, we'll lose our individuality and in the process, the things that make being human fun. Why would you ever learn to play the guitar if you have infinite access to every guitar recording ever? How could you ever develop independent political thought, if you're plugged into the matrix 24/7?
Oh, great, so not only can choose to not resume where you left off when you intentionally shut down, but that choice will force you to completely lose your place after an unintentional restart due to an update. Genius!
This is not a scientific term, nor does there seem to be any research on what this is and whether the premises are right. E.g. the 'multi-tasking' research found very clearly that there's no such thing as multi-tasking, rather we switch rapidly between tasks and this context-switching is not very efficient. I don't see how 'continuous partial attention' would be possible in light of this.
There was never a bar that a term or concept had to be "scientific" to be valuable, interesting, enlightening and so on...
It's about detecting predators before they eat you or prey before you starve or mates before your genes leave the pool. Modern networks are just a modern source of that data.
We're hard wired for CPA by a billion generations.
I also take this idea, that predator detection predates humanity and goes deep into our ancestral roots, to be the commenter's point.
There was also probably at least 500 million years of only single cellular life.
1 billion seems in the neighborhood of the number of generations or maybe even a few orders of magnitude too low.
