Thanks for sharing your predictions. In terms of cash or currency in general, due to the devaluation of currencies in most part of the world, that makes money valued by points in the future rather than monetary value. The inflation of prices, making a paper note with no value/meaning.

On another note, this explains how currencies are being a monopolized product in the hands of the few. middle-calss can not retain and save money any more due to inflation what I call devaluation.

Search engines, the way how I imagined them is to become an engine that put the puzzle together for any searched topic and create a full picture for the researcher. look at my case study here with simple example on what I am imagining. https://www.ahmedali.one/portfolio/project-four-2lcdy-wbaxt
