key points • Technology blurs the line between living and non-living machines, and
between our bodies and the outside world.• Technology is affecting the way our brain develops.• Modern technology has helped us develop drugs for medicine.• We are evolving to adapt to technology

arm’s reach every hour of every day.
Article 2 – “Do we take technology for granted”
http://electronicdesign.com/archive/do-we-take-technology-advances-granted
“Today's relentless advances in semiconductor technology, which allow the doubling of chip complexity about every 18 to 24 months, have happened so regularly that we have been able to schedule our use of next-generation technology without any misgivings. System designers can start crafting their solutions well over a year before the process they need will be ready for production.This confidence in the ability of semiconductor fabricators to keep up the pace of process improvements has, for the most part, been right on target. But as critical dimensions start dropping below 0.13 µm, the fabrication challenges continue to increase. This may delay the transitions to each succeeding process generation. Just scaling the mask dimensions to implement the smaller features is only the first of many changes in the complex fabrication flows that will implement the future generations of VLSI chips.Walking through the exhibits at last month's Semicon show in San Francisco and San Jose reminded me about the complexity of the overall fabrication process. More than 2000 companies demonstrated their best efforts to move the industry forward, exhibiting developments that ranged from ultrapure liquids, gases, and other materials used during fabrication to the dust-free carrier chambers used to move the wafers from step to step.
But can we continue to expect the industry to keep its improvements on the same 18- to 24-month timetable? Or will that timetable stretch out, so that each new production process is instead introduced on a 24- to 30-month cycle? This may happen due to a number of reasons aside from the current economic slowdown. One might be the metrology needed to achieve and then measure the impurity levels. Another reason could be the lithography systems and the ability to create the fine-featured masks that pattern the wafers.
Many companies in the semiconductor industry are working in concert to achieve the combination of advances necessary to create chips that employ critical features an order of magnitude below those of today. But what will you design over the next decade or so that will require a billion transistors on a chip, aside from a memory array? Today's most complex CPUs, including large on-chip caches, are only 30 to 40 million transistors, and a few specialty graphics engines have already surpassed 50 million transistors. Will future chips be large multiprocessor arrays that implement system-level solutions? Should we rethink system architectures to better leverage large amounts of memory?Moreover, will the design tools, test tools, and the platforms they run on be up to the challenge, or will they "break" or run out of steam as circuit complexities increase? Are we taking for granted that we will always find ways to overcome these challenges, or are we reaching some technology limits?”
Article 3 – Technology addiction in Teens
http://everydaylife.globalpost.com/technology-addiction-teens-11134.html
“Many of today's teens spend much of their time with their faces buried in a computer monitor or smart phone. Moms and dads who would prefer that their teens’ faces were buried in books might suspect the cause of this phenomenon is technology addiction. However, parents need to understand the specific symptoms of technology addiction before making a judgment”
Key points in article:
• When stressed, bored teens tend to go to their phones and social media
• Technology addiction can result in poor academic performance
• Can pull people away from social engagement
• Online video games are among the most addictive devices.
Attractiveness of Technology
“Teens are particularly susceptible to technology addiction for several reasons. First, teens tend to have poor coping mechanisms. In the face of stress, they often turn to what’s comforting to them, usually something easy to focus on, including online videos or social media sites. The increased convenience and widespread availability of technology makes it easy for a teen to whip out a mobile device and switch her focus from the real world to the virtual world. Also, in the teen years, self-identity is crucial. Most teen struggle with understanding who they are and how to present themselves. One attraction of technologies such as online video games and the Internet is the anonymity it brings, allowing teens to express themselves without putting their ego at risk.”

Risks
http://everydaylife.globalpost.com/technology-addiction-teens-11134.html
“Technology addiction can have several negative effects on a teen. The attractiveness of anonymity, for example, might pull a teen away from social engagement. After all, a teen might embarrass himself at a party, but that’s something not easily done online. Such an avoidance of social settings, in combination with the draw of the Internet, could lead to a teen shutting himself off from his peers. This also leaks into family life. A teen who overuses technology or uses technology to cope with problems might refuse to engage in family discourse or family activities in favor of using the newest gadget or phone application. And, as in addicted adults, addiction can affect a teen’s work and academic performance. A teen who rushes to get online after school neglects his homework. A teen who is texting in class neglects the lecture.”
Characteristic of Addiction
“Enjoying technology on a frequent basis does not necessarily mean your teen is addicted to technology. According to Young, less than 5 percent of teens suffer from a technology addiction. Many of the signs of addiction are behavioral. For example, compulsions to use technology in favor of rare and exciting life events, such as parties or vacations, might signify addiction. In addition, attitude changes in your teen might be cause for alarm; sudden depression, loss of self-esteem, and problems paying attention are symptoms of Internet addiction.”
