Final answer:
The dispersal of new technologies today would likely occur faster than historical precedents like the Iron Age, due to globalization and technology. Opportunities for disparities still exist but are shaped by economic and political factors.
Step-by-step explanation:
The timeline of the Iron Age varied across different regions of the world, with technological advancements not spreading uniformly. In ancient times, the discovery and use of iron evolved independently in various locales, as seen with sub-Saharan Africa developing iron smelting before it was introduced into Egypt. Today, however, the dissemination of a new mineral or technology would likely unfold much more rapidly due to globalization. Advanced communication channels, international trade agreements, and the interconnected nature of economies encourage the swift spread of innovation. The rapid adoption of mobile phones and the internet across the globe, regardless of economic status, exemplifies this trend. While disparities still exist, they are more likely to stem from economic or political factors rather than the isolated development of past eras.
