Using technology is what is making the world go round in the 21st century. Computers are used for personal stuff, school, paying taxes, transportation, etc. With all the pros that there are with computers, there are cons also. There are obviously more than 3 ways technology or computers have made the world more safe and less safe. Emergency or Law Enforcement services using computers have made the world way safer because it’s easier for them to track a call while taking information from the caller or find information on a criminal they are looking for. Having the slightest amount of information like a license plate, a tattoo, or a nickname can give these workers the ability to search their databases to find exactly who they are looking for. Coming with these databases that have everyone’s personal information someone can hack into the system to find the information of anyone they are looking for, which nonetheless, would make the world a less secure place. It’s more efficient to use computers in the classrooms because the grading can be done automatically, paper is being saved, and more importantly it’s slightly less work for the teachers. With great power comes great responsibility, I say this because it then becomes easier for your students to use the internet while doing their work. Lastly, transportation makes the world safer by keeping drunk drivers off the road with uber and lyft. There is also a disadvantage with taking these types of transportation such as; you are in the car with a complete stranger, they now have your home address or last known location, and you never know someone’s true intentions. With all this being said I believe that one day the world will strictly rely on computers and technology. The masterminds behind any and all technology should be finding out ways that nobody can hack or get their hands on others personal information. One day the new saying will be “Technology makes the world go round.”
