Dear Mr. Joseph Tham ,if the impact of social media only causes hatred, division, dissemination of false information and so on, it is bad, natural if disbanded. but social media can improve by filtering information that has a negative impact, this is the task of the information technology team in social media operators, by changing the features of social media applications as tightly as possible. if social media is in the hands of the wrong person, the result will be bad!
if the cost is greater then it is detrimental, if the benefits are greater then it can be considered profitable, but in certain countries such as Indonesia tend to be detrimental, used for things that are not useful, the government has threatened to close it, but it is uncertain when.
I think we have to find the information and data to answer this question. We cannot simply talk in the abstract. Also, we need to consider the opinions of the users.
