It’s about time.  Writing in the New York Times, Alina Tugend calls bullshit on multitasking

David E. Meyer, a professor of psychology at the University of Michigan,
and his colleagues looked at young adults as they performed tasks that
involved solving math problems or classifying geometric objects.

Their
2001 study, published in The Journal of Experimental Psychology, found
that for all types of tasks, the participants lost time when they had
to move back and forth from one undertaking to another, and that it
took significantly longer to switch between the more complicated tasks.

You know how God managed to create the World in seven days?  He didn’t have to stop every 5 minutes and answer the damn phone.
