If you are an Instagram user, at some point, you care going to be interested in the various metrics such as followers, number of posts by a certain user etc. You might want to compare these metrics between different users or to find out the number of posts with a certain hashtag etc. The casual way to do it is to go the relevant Instagram page and look at the metric and write it down somewhere, and go to next and so on. Clearly this is not ideal strategy if you want to look at a few hundred pages. It would be neat to get this data in an automated manner.
It may seem like the world is descending into total chaos, violence, and destruction. War in Syria, Ukraine, Yemen, Islamic state, migrant crisis, Ebola, plane crashes, earthquakes, tsunamis and what-not. The more news you watch, the more worried you will be. This is because the news outlets tend to focus on spectacularly negative instances. Violence, atrocities, and hatred are thrown into the spotlight and into the lives of common people. With the ever increasing digital connectivity, it is easy to disseminate information and to absorb information at an unprecedented level. Relatively smaller incidents have a larger voice. As said by Ray Kurzwil, “The world isn’t getting worse, our information is getting better”. To appreciate the world we live in, we have to put things into a wider context.
The fact is that humanity has never lived in a better time than now in pretty much every aspect you look at; war, violence, diseases, poverty are all at the lowest it has ever been. Of course, there is still a long way to go, but this is the best it has been since the beginning of humankind. To prove my point, here we evaluate human progress using some real data and simple time-series plots. Most of the data and information was obtained from OurWorldInData.
