Interpreting 140 signs at a time

I am re-reading Nicholas Carr article published in the June issue of The Atlantic : "Is Google Making Us Stupid?".
I am reading it the way Carr worries about what reading has been shifting to these days, in chunks, not in linear fashion, while skipping, which means by the way ever going back. What will be speakers, speeches, discourses, verbal expressions to be interpreted in 30 years time? What will be interpreter's training models in that perspective?
