Entry 9:  Three ways that computers have made the world safer and less safe.

Computers have undoubtedly had a profound impact on society, both in terms of making the world safer and less safe. Here are three ways that computers have made the world safer and three ways they have made it less safe:

Safer:

1. Improved security: Computers have enabled the development of advanced security technologies, such as biometric authentication and encryption, that help keep people and information safe from unauthorized access.
2. Emergency response: Computers have revolutionized emergency response systems, making it easier to detect and respond to crises. For instance, emergency services can use computers to track the location of callers and send help quickly.
3. Medical advances: Computers have played a vital role in advancing medical science, from the development of new treatments to the use of virtual reality in patient care. This has improved health outcomes and made the world a safer place for people with medical conditions.

Less safe:

1. Cybersecurity threats: Computers have made the world less safe by providing a new avenue for cyber attacks, such as phishing, hacking, and ransomware. These attacks can compromise sensitive data and harm individuals and organizations.
2. Social media: While social media has made it easier for people to connect and share information, it has also made the world less safe by enabling the spread of false information, cyberbullying, and hate speech.
3. Automation and job loss: Computers have also made the world less safe for workers, especially those in low-skilled jobs that are vulnerable to automation. This has led to job loss and economic insecurity for many people.

In conclusion, computers have had both positive and negative effects on society, making the world both safer and less safe. While they have brought many benefits, they have also created new risks and challenges that we must address to ensure a safe and secure future.
