Which Flattener is Having the Most Impact

I think it is difficult to arrive at any one flattener in regard to its biggest impact on the world today. I think, considering the current global situation with the pandemic, that the development of the browser in 1995 has to be ranked as a very important innovation, since we would not be able to avail ourselves of the other resources today if not for the capability to access the Web. Of course without some of the other innovations introduced since 1995 we would still be limited as to what we could do, insofar as communicating electronically.

I still believe that because of Netscape and the browser many other developments have come about since then that may not have been introduced otherwise.
