What affects will cellular phones have on our brains in the next century?

I know nothing of the answer to the title of this blog, but I worry.  We have already seen the programming of people who respond to a ring tone, a buzz, or a vibration with such immediacy that it is sure to change the way our brains function.  My father always told me that the sign of maturity is the ability to delay gratification and if this is true, the immediacy with which this generation of youth solve problems, retrieve information, and respond to each other using the cell phone constantly in hand, may change the way the brain acts over the next centuries.  If reading in only 3,000 years old, the cell phone may be responsible for making changes in the brain in the very near future.

In Proust and the Squid, near the end of the book Wolf begins on of the chapters with "every society worries over the future of its youth and the challenges they will face". (212) She quotes Ray Kurzweil whose name i had heard, but I googled him to understand his importance an American author, inventor, futurist, and a director of engineering at Google.  He has suggested that "100 trillion neural connections in our brains extend exponentially through the technological, non biological intelligence we have invented" (qtd in Wolf p. 213).

I am by no means a scientist and I really have no idea what that means, but cell phones may alter brain activity in a very real way.  The title of her chapter is appropriately called "Conclusions: From the Reading Brain to "What comes Next".  I truly wonder this.  What comes next.  Studies have show that "cell phone use was associated with increased brain glucose metabolism (a marker of brain activity)"
