When people have wealth and resources that do not match their capabilities, those resources do not lead to innovation and revolution, but only to more suffering and conflict. Congo is a very good example. About a quarter of the tantalum ore mined in the first decade of the twenty-first century came from Congolese coltan. Coltan, short for coltan, is an unrefined mixture of two metallic ores from which tantalum can be extracted. Tantalum is an excellent conductor of electricity and is mainly used in the miniature capacitors that make our increasingly miniaturized electronic devices work. The huge profits have made an already troubled country even more chaotic and disorganized, and forty percent of the mining workforce are children (about six years old). And like other miners, many of them have been exposed to mercury, uranium and other heavy metals. What most of us don’t realize is that the elements of the electronic devices we use in our hands contain such a bloody story and history. For all the talk about Web 3.0 and decentralization, are we just dressing up the same old systems? Even with blockchain or decentralized networks, the question remains as to who will benefit from it. Countless people are profiting from the growth of this industry, so how do we ensure that the system is free from graft or corruption? Although a lot of things are now data-driven, behind this invisibility, it relies on a very large amount of physical infrastructure and manpower, with some areas and resources of manpower exchanged for our current society. While enjoying these technological conveniences, can we really realize the costs behind them? In the next historical process, how can we promote the development of AI technology while ensuring that we do not repeat the mistakes of the past?
