it would be interesting to have an application where one can enter a date and receive a list that describes the life situation of common people at the time by opportunities and knowledge that existed.
here are notes about the data such a tool would need to have.
the idea relates to what is known as a tech-tree of civiliziation, alluding to the hierarchical progression of abilities often seen in video games. such a tech-tree would be a significant oversimplification and it is therefore important to choose carefully what it should simplify to. in this case, the target is a basic when-and-where classification of common availability of impactful opportunities.
since availability can fluctuate, some minimum stability time limit will probably be useful. definitions of what it means for an invention to reach critical mass, so that the results are widely available, are also relevant, as are definitions of what it means for an invention to be meaningfully impactful to common people.
it is possible to create a tuple of variables that define one datapoint.
for example:
(time, location, concept)
mobility: the ability to move objects and humans to different locations
