Challenges and Opportunities
The new developments in information technology bring both challenges and chances for everyone. One big challenge is keeping our personal information safe from hackers and data breaches. We also need to make sure that new technologies, like AI, are used ethically and don’t discriminate against certain groups of people.
Another challenge is making sure everyone has the skills they need to work in a digital world. Many jobs are changing because of new technology, so people need to learn new skills and keep up with the changes. Some people also don’t have access to the internet or know how to use it, which creates a gap between those who have access to information and those who don’t.
