Technologies change fast and affect almost everything

Technologies change very quickly, it is difficult to predict. Precisely, many experts think that Machine Learning has the greatest potential to change many things as it can affect every industry, every business, every country and everyone's life. This technology can analyze a large amount of data in a very short time. It can optimize many operations from factories to offices. These days, machine learning technology is still changing. Together with fast computers and biological knowledge, it will become a very powerful technology in the near future. Imagine that one day, your health can be monitored 24/7 with a small biometric device worn on your wrist. It will be able to determine your blood pressure and your heart beat every minute, or even find out a very small tumor before you realize that something wrong with your health. By contrast, this device can also fight against  by taking your personal information for political or commercial purposes. Therefore, we need to prepare for the big wave of technological change by learning continuously and updating our skills that will match the need of job market in this technology-driven world.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
