One way that computers have made the world safer is providing extra protection from attacks abroad. We can use these systems to detect any kind of attack that our adversaries may try to engage with us in.

These computers have helped protect against numerous accidents including distracted driving where some could have potentially been killed as a result. Another way that computers have made the world safer is technology like security cameras and certain features. Security features on houses have helped protect against a possible burglary from happening. Some systems will even call the police, they will call the fire department if there is a fire, and even a medic if someone falls or is having a medical emergency.
One way that computers have made the world less safe is that some of our personal information is now online. For example, buying something from Amazon, Walmart, eBay, or any sketchy website where card information and address is entered in. People may hack into or gain access to that information and do whatever they want with it. Another way that computers have made the world less safe is that people can scam others to get money or access to their bank information. For example, when someone calls on the phone saying you owe them money and that the sheriff will show up at the door.

Another country can attack our infrastructure and put a halt on things like our power grid, airports, railways, and even the supply chain.
