7 Technologies That Changed The World


Is Technology a boon or bane? This has been a controversial theme for decades. While some argue that technology is negatively impacting society, we cannot entirely negate the positive outcomes of technology. Even though technology has brought about adverse effects like violence, behavioural issues, climate change, etc., it has also significantly transformed our lives. For instance, if it was not for technology, you wouldn’t even be reading this article online. This blog discusses various technologies that have made a positive impact on society.

How Has Technology Changed The World?

In the last two decades, technological advancement has benefited almost every sector. However, there have been remarkable changes in some fields like Media and communication, climate, and healthcare.

In Media and Communication, the rise of social media platforms has had far-reaching effects. It has allowed people to stay connected with each other through phone calls and video calls. Technical tools enable companies to interact with their customers, understand consumer behaviour and provide better products and services.

With every passing year, the climate change struggle is becoming more real. Therefore, the majority of the world’s companies are taking action for sustainable development goals. Companies invest billions of dollars in infrastructure projects and new technologies that will help to slow down climate change. Many startups are focusing on carbon capture technology that aims to reduce the carbon dioxide levels in the air.

The integration of technology in the health sector like X-ray machines, monitors and surgical equipment helps in the timely and efficient treatment of fatal diseases. It has reduced the mortality rate.

Technologies That Have Changed The World

The Interplay of Science and Technology has a deep-rooted impact on society. Almost everything around us, including home appliances, infrastructure, automotive, health equipment, educational tools, all are made available to us through technological means. Here are some remarkable technologies that have played a crucial role in changing the world for the better.

1. Internet of Things:-

IoT is an integration of sensors, software and other technical tools. It facilitates communication, connectivity and data exchange across different servers. In simple terms, things connected to the Internet are called IoT. The best examples of IoT devices are smartwatches, home security systems, wi-fi, smart fire extinguishers, automatic cars and AI home appliances, all of which have made our lives easier.

2. Artificial Intelligence:- 

AI machines understand human behaviour and actions and perform similar tasks in the same situations. It includes chatbots, self-driving cars, maps, facial recognition apps, and autocorrect features. AI technology has made everyday tasks quicker and easier. This technology also helps differently-abled to perform daily tasks with ease.

3. Drones:- 

During wars and natural calamities, rescue teams use drones to deliver essential items like food and water supplies to the victims. Farmers use drones to monitor their crops and agricultural lands remotely. They also are handy tools for geo-mapping, surveying land, and monitoring forest reserves for wildlife preservation. Many eCommerce businesses across the world are also using drones to deliver customer packages.

4. Videoconferencing:- 

Our lives have drastically changed after the introduction of videoconferencing technology. We can connect with anyone at any place in the world. It has made communication easy, especially during the pandemic where video calling was the only option that allowed us to connect with people. 

5. Virtual Reality:- 

Another technology that has a significant impact on society is virtual reality. In the business sector, virtual reality tools help customers view goods from a 360-degree angle and make better choices. Also, many ed-tech startups are using virtual reality technology to explain practical concepts to children. It helps children to understand better.

6. Data Science:- 

As they say, data is the new oil. It has become an integral part of our lives. Organisations use various technologies and methods to filter relevant data and analyse the data to prepare relevant statistics. This is known as data science. All statistics and figures that we can read today are because of data science. At a large scale, data science helps countries monitor their growth and development, allows the authorities to take necessary measures in a particular sector, and allows countries to compare their growth.

7. Cloud Services:- 

Data Breach is a grave concern for the world economy. Every year companies lose billions in data breach incidents. Cloud services help mitigate such losses. These platforms have several high-security levels that protect data. Cloud computing services are beneficial for both companies and individuals.
