Technology is now a big part of our society and our predictable future. There is little room for people who wish to live without technology, and luckily, it is still advancing at a rate that has helped stave off stagnation.

Smartphones enable people to stay in touch, even over long distances, and they are relatively safe and reliable to use. There are devices that people can use to communicate with plus at the other end of the planet and getting and keeping in touch with other people is very easy.
The disadvantages of smartphone is that it means people no longer need to meet in person as much, and interpersonal relationships are suffering worldwide because people are communicating through a small handheld device. A lot of people have smartphones and they use them almost semi-continuously, including in public settings when they could be making new friends, finding new lovers, and interacting with their current friends.
The advantages of the internet are that people can communicate over vast distances and can gain access to information and get answers to their questions very quickly. The disadvantage is that the Internet isn’t moderated in the way that people think and lots of it is filled with misinformation and outright lies.
Even brand-named websites which have a lot of trust are not accountable for what appears on their own websites. Even respected and branded news sites have stories that have passed through many people’s hands and originally started as lies with zero accountability throughout the dissemination process.
In conclusion, technology brings about such a lot of advantages. However, it’s people’s duty to use it in an appropriate way to make it beneficial.
