Its not just about revealing unethicall behaviour though. New information that promotes progress have a far wider reach today then just 20 years back. Theres a shift going on at a speed previously unimagined.

For example, in approxiamtely around 1950 there was a study ”revealing” that fat was a primary culprit to heart disease, turns out this is not the case and that carbs is one of the main reasons and a decrease in fat consumption can actually be contributing to this. The last 15 years this has come to surface at a rapid speed. Thoose who gains from for example diabetes medication tries to fight this new revelation but the ones advocating fat is gaining grounds due to science backing them empirically but primarily due to the amazing power behind spreading the word online.
The study in the 1950 advocating the fat scare was actually poorly done and would not have held its ground if it hade seen the light today for that long. Theese are some of the positive changes made due to the spread through social medias and the internet being public domain.

Another good example would be the #metoo movement that would not have came out into the light with souch force if it where not for social media/internet.

Just a thought on equality, when I speak of equality I do not mean it just from a feministic standpoint but also when it comes to redistribution of wealth and social security.
There is still emense unequality in the world, at times the cracks are widening, but in the long run I believe the rift between poverty and wealth will be bridged and get much closer then it is today.

As for the change of the human nature, thats a much slover process indeed. For us to catch up to this rapid change happening around us will take time. But due to the technologicall progress thats happening in this time and era it will have a turbo boosted effect on us as well. We are still in its infacy. In a way, social media/internet has brought us both closer and farther away from eachother, but that gap will close when we look up from our screens and embrace the world around us aswell as the world beyond our reach that we interact with online.
