Gambling industry won't disappear as this activity has been with humanity since the beginning of time. It evolves thru time and so we can see the varying forms of this industry depending on the technological stage that we have. So I don't think this activity will just be wiped out from the face of the earth.
And since we won't see the eradication of this industry, what we can do is just look at the positive side of it. There may be negative side but it is the same for all industry, right? Also, do take note that anything that is too much is indeed bad for people. So if you regulate your gambling habits, I don't think you will be in trouble.
Gambling strikes a chord with many people, and this is because deep down many people love to take risks just for the sake of it, this is like those that jump out of a bridge or do something dangerous, many people wonder why they do it? But they do it because they like the feeling of doing activities that are inherently risky.
And gambling does the exact same thing, as people love the idea of putting their money at risk and the possibility of even earning a larger amount, so once we think more profoundly about gambling, it is obvious that no matter what it is done, gambling will never disappear.
It really will not disappear anywhere, because every person has hope for a better life. Everyone wants to believe that the life they are living now is only temporary, and the best will be ahead. But often the only way to improve your life by arranging a life change is to go to the casino and play to the last dollar. And it's enough for gamblers to know that someone has won so much that they believe that this gambler will be able to change his life through the casino.
