Connecting

Description about this Video from Original Source

————————————————————————————————————–

The content of the video is all about what I have thought about the advent development of wireless technologies including internet and mobile technologies. Connecting is the biggest issue of the 21st century as people want to be connected, getting attention from others. Radical improvement of wireless technologies have totally reshaped the way that we communicated others and now it enables us to communicate anyone in anytime without any difficulties we used to have in a decade ago.
Then, how is the life with better connectivity? Are we happier than before along with being connected with the flood of information and connectivity? Apparently, there is no way I can deny the advantage of technologies in terms of convenience. However, in terms of better quality of life, it’s not quite yet.

I believe this is the time we need to consider the quality of experience instead of concentrating on sole technological development. How do we make a world with better life quality, not just filling with all convenient devices,which at some point degrading humanity. How can technologies make people more human?
These are the questions that will follow me for another decade.
