In: Statistics and Probability
All i can say to you as an statistics expert that the future is unpredictable.Even in statistics the things we predict are based on some assumptions. But the truth is we do not know exactly what is going to be happen in future but yes we can predict some things as in near future if technological growth will be at same constant rate then by 2030, it is possible that first human have stepped into the mars. And as a japanese company promised may be the space tourism is possible for humans. We may have solution to the fusion reaction which will help humans to grow in the field of technology. Socially if we can say then the only thing i say that we humans are social species we are dependent on each other either it is for food or for any basic requirement and we grow because we socialise. Yes, there are many political, religious as well as many differences within many countries but moving towards the development and science may be one day we will find the solution of this problem as well.
Day-to-day every government in the world is trying to reduce the difference between the income inequality, i cannot say that income inequality by 2030 will reduce but yes i can say that it is pretty much difficult task because of the world's population, there are 7B people on the earth right now and the number is increasing but resources are not those who have access to these resources are considered to be rich , reducing the income inequality is pretty much difficult task for every government and if we were successful towards this goal then it'd be greatest achievement at all.
