Technologies can offer safety and protection for people

Computers and Technology

inn [45]3 years ago

Answer:

True

Explanation:

This is certainly true. If the technologies are being used correctly and ethically then they are certainly going to safeguard the people and make their life easier and better. However, if the technology is not used ethically, and technology is given in the wrong hands, it can be very lethal. Like we can consider the nuclear bombs. If a nuclear bomb technology is being given to the wrong hands then they can use it to do the destruction, and that will not be good for us. And all should understand this. Proper and ethical use is a must for technology.
