Article 1:

This is about AccuWeather using anonymous data from its users even after the user says they do not want to share their data outside of the app. The reason they were able to do this is because in their question they specified that they would not use the information through the app while it runs in the background, but they are using the anonymized data outside of the app. This article shows that apps have access to your data, which is not a new idea, and that they can use it without your knowing. 
Article 2:

Cons:

GPS would know if you were speeding, minor crime preventionData leaks, new technology always has bugsHardware replacement / upgradesBody migrationMRI scanners cannot scan with metal implantsNo universal standardsor all in one chip Micro chipping in humans has a wide range of possibilites, many of which are beneficial and would improve the lives of many. Being able to protect children and elderly, for example, would be a paramount civilian safetly improvement. Because there are no universal standards it seems this technology will be developing for a while, though. The inconvienience of getting multiple micro chips, or having them taken out and put in a multitude of times is highly unappealing.

The Amazon Echo Dot is a hands-free, voice controlled crevice that uses the same far field voice recognition as Amazon Echo. The dot has a small built in speaker and can also connect to your speakers via Bluetooth or through an audio cable. The dot connects to the Alexa Voice Service to play music, provide information, news, sports scores, weather, and more.

With the ability to say, "Alexa, tell me a story", or many other prompts, finding out what the device has to offer is entertainment on its own. The dot is a smaller version of the original Amazon Echo, but is unlike any device yet. In some fashions the dot is similar to Siri on Apple products, but it is redesigned as its own multipurpose item as opposed to being embedded within one. The dot makes playing and changing music simple with the ability to play specific songs or radio stations. Another handy feature is being able to create …
