It is not encouraged and does not exist in practice.
Technology played a major role in European expansion because it had always been very difficult to accurately and safely navigate ships across vast distances of open ocean waters. As maps and navigation tools improved, explorers could travel longer and longer distances to find new undiscovered lands. Another grand technological advancement that allowed Europeans to colonize the world was the invention of firearms. If you happen to run into some unhappy indigenous people in your brand new colony it is much easier to tell them to get lost if you have a gun with you.

While Aborigines did not know of the wheel prior to European settlement, they did have technology. They fashioned spears, and developed a modification that allowed them to throw their spears over longer distances. They developed various types of boomerang as well.
Key technological advances that allowed Europeans to explore new areas during the Age of Exploration included the development of the astrolabe and compass for navigation, the improvement of ship design with the invention of the caravel, and the spread of the printing press for sharing geographical knowledge and maps. These tools enabled European explorers to venture further from their home countries and navigate across oceans with greater accuracy and efficiency.

traveling greater distances.
Technological innovations like improved navigational tools (such as the compass and astrolabe) allowed explorers to more accurately navigate across oceans. Additionally, advancements in shipbuilding, like the development of the caravel and improvements in sail design, enabled ships to sail longer distances and withstand harsher conditions, making long-distance exploration more feasible.
The steam engine, particularly in the form of steamships and railways, was one of the most important inventions for spreading European influence in Africa. It enabled faster and more efficient transportation of goods, people, and military forces across vast distances, facilitating trade and colonization. This technological advancement allowed Europeans to penetrate deeper into the continent, establish control over resources, and exert political influence, significantly shaping Africa's socio-economic landscape during the colonial period.
