Technology these days is improved more than before. What we previously knew before as a floppy disk now is a thumb drive that improved its storage capacities to more space and its size to smaller that we could take it anywhere. Technology has advanced in different categories such as medicine, education, marketing, and others. The use of it depends on the person how they use it and how they help contribute to society.
In the healthcare sector, technology has improved taking care of patients. I know that today if one person lost a part of the body, they can replace it with a 3D model imprinted like half of an arm or leg. The evolution of technology has brought us different ways to fix problems like finding a new solution for diseases or disabilities. Some people have a problem hearing. Technology can help us find a solution like hearing aids. A hearing aid is an electronic device that notifies, amplifies, and changes the sound to allow better communication. Hearing aids receive the sound through a microphone, which then converts the sound waves into electrical signals. The amplifier increases the volume of the signals and then sends the sound to the ear through a loudspeaker. That would help a lot of people with a problem hearing. Also, they could find a cure for cancer to prevent millions of people to die from it. The researchers inject DNA nanobots loaded with thrombin into the bloodstream (currently in animals) to treat cancer; when the blood vessels that nourish the tumor arrive, the nanorobots detect the presence of nucleolin thanks to the DNA aptamers and are activated; thrombin initiates a coagulation process that ends up blocking the flow of blood to the tumor and it dies. The treatment with nanorobots showed no signs of toxicity in the treated animals. The concentration of nanorobots in the body had decreased, which meant that nanoparticles could be eliminated by the body naturally. The use of technology in the medical sector is to improve the health of the person, but some people used it for bad things. For example, when I watched a movie about a company that created a virus that makes people sick. They put the virus in the food and sold it on the market. The company was the only one with the solution to the virus because they themselves had created the virus. Their intentions were to take money from people who got sick and could charge whatever they wanted to be the only company with the cure. The problem isn't technology. The problem is people and how they use technology in the wrong way.
We see now that education has changed with technology. Professor and students’ massive amounts of information (books, audio, images, videos) are available at one’s fingertips through the Internet, and opportunities for formal learning are available online worldwide through the Khan Academy, MOOCs, podcasts, traditional online degree programs, and more. Technology enables forms of communication and collaboration undreamt of in the past. Today some students study online, and teachers teach online. Students can share what they are learning with students in other classrooms in other states who are tracking the same expedition. We see that some school have their own projector screen in each classroom. Technology brought us a way easier to teach and learn. Before, the teacher had a problem with teaching without complete information. Now, they have access to all information to teach with a computer with the Internet and a projector screen. It is easier for teachers to create instructional materials for enabling new ways for people to learn and work together. The walls of the classrooms are no longer a barrier as technology enables new ways of learning, communicating, and working collaboratively. Sometimes for people is hard to go in person to learn in class because they are busy, don't have time, and it is too far. The class online brought us the way that people with those problems can get a chance to give the class in an easy way. Online classes have their disadvantage and advantage. The most obvious disadvantage of the online environment is that students and professors are physically disconnected. That means a class where the instructor and students are together online simultaneously and can interact in 'real time'. After all, there is something personal about sitting face to face with a student, determining by conversation or body language what the student does or does not understand. It is useful to stand in front of a classroom and talk, explore, read facial expressions, sometimes argue, and often laugh together. Even in the best online classroom, this just isn't possible. Some of the advantages to take classes online are a variety of courses, lower cost, flexibility, avoid commuting, and learning in a comfortable environment. Online education is generally less expensive than face-to-face courses. For example, costs that are related to transport, such as fuel, parking, car maintenance, and public transportation costs don't affect the online student. Online courses offer you flexibility so that you can fulfill your other occupations and responsibilities, without leaving aside the continuous education. You can simply stay in your pajamas and do your homework for that day. Learning in your own environment makes the task easier for students. They are no longer distracted from their work by other students. When I was at school, one day we have a test on the computer, and it was online on a page that the teacher created. My friend told me that the answer to the test was on the source of the page because he did the test in 5 minutes. I realized that was true and I took advantage of that. The way that I cheated was unfair. My point is sometimes the use of technology is good and beneficial for us if we don't use it in the wrong way.
Technology on the market has a connection with this generation. A company can up its sales using advertising on cell phones, television, radio, podcasts, and social media. The market can help distribute or publish new advanced technology. Before, we couldn't buy stuff on the Internet. The impact of technology on the company has been increasingly important in recent years in which new technologies have been incorporated and a great advance has been made within technology itself. Each time the technologies facilitate the tasks of the company and product innovation, which means that companies that do not add to these technologies are left behind. There are many technologies of high importance in the company that has grown in recent years: new production tools, new management tools, new training tools, new computer programs, new hardware, new work devices, new communication tools (the Internet, email, social networks), etc. Things have changed a lot since faxing was a very important element of communication and many companies had to do many tasks manually. It is clear that technology has had a very large impact on all companies, from which all high technologies can be allowed, which can only afford a new work tool, those that use the Internet in the company or those that have their page in social networks. All companies, in one way or another, have an important dependence on computer science and new technologies. This is partly good, as long as everything goes well. Now, we can see a thousand stores on the Internet that you can buy or sell. For example, Amazon, eBay, Alibaba, Mercado Libre, and others. Today technology is so advanced that my sister told me that 'Alexa' (the smart speaker) can hear us. One day she was talking about how she needed a new computer. The next day, she was using the phone on Instagram and popped up 5 advertisements about computers. Technology is awesome, but it should be a limit because almost nobody likes that someone or something invades their privacy. What happened with my sister is that the smart speaker is programmed to do those kinds of things. Programmers make codes so that when they hear something they need or want; they help you find where we can get it.
The use of technology can make a difference in the world, but there will always be people who use it incorrectly. With technology evolving, humans improve their physical and mental abilities. The misuse of technology can bring us to extinction because the human being is imperfect and we make mistakes. In technology, an error can cause big problems. That's why we have to teach people the use and its consequences to avoid chaos.
In conclusion, technology and its evolution are always good for us, but how people use it could see that technology is bad for us.
