Helpful ideas:

Introduction: robots are widely used in the food industry and medicine/ they have advantages and disadvantages

Body: advantages: fewer human workers, errors, and defects

disadvantages: power failure, malfunction, hackers

Conclusion: help humans improve their lives a threat to humans or not?

Suggested answer: A. I. robots are widely used in areas such as the food industry and medicine. Obviously, they bring advantages as well as disadvantages.

The advantages of intelligent robots are countless. Robotic machines are countless. Robotic machines can replace the human workforce in industrial assembly lines because they cannot only complete tasks faster than humans, but also make fewer errors. Furthermore, unlike humans, they take no breaks. In modern manufacturing plants, one out of every ten thousand workers is a robot. That is the reason why robots are so widely used in the automobile and electronics factories.

In hospitals, A. I. robots can operate on patients, and help doctors to discover damaged organs in patients. They also help experts to do research on any serious side effects caused by the interactions of different medications on patients that can lead to complications in treatment.

The disadvantages of A. I. are undeniable. Robots and other robotic machines are designed and programmed by humans. Therefore, they can be attacked by malware or viruses or disabled due to power failure. In such cases, the computer systems will crash and A. I. devices will become useless machines. Another disadvantage is that the computer operating systems could be taken control of by hackers, causing misuse of robotic devices. This could potentially be dangerous to human lives.

In conclusion, robots benefit humanity because the aim of their creation is replace people in stressful and dangerous jobs, and make their lives better. But relying on them completely is dangerous, because so much can go wrong with them. In the end, the advantages outweigh the disadvantages.
