Neil Postman, a smart guy who studied how we use media, said that technology is like a double-edged sword: it can be amazing, but it can also cause harm.
He showed how cars, for example, made it easier to travel but also led to air pollution and traffic jams.
Postman believed that we need to be wise and think carefully about how we use technology, just like we wouldn't just grab a sharp knife without knowing what to do with it.
He said that technology can be a powerful tool, but we need to use it responsibly and with a strong sense of what's right and wrong.
