As self-media creators, we need to rewrite an article to express it in more modern language, clarify the meaning, improve the wording, and remove unnecessary words. Here's a rewrite of the original article:
Why did billionaires venture into the deep sea in search of the "Titanic"? The ocean is very different from the land and is a place on Earth that few humans have fully explored. Our knowledge of the ocean accounts for less than 5% of its expansiveness. Although we divide the oceans into territorial and high seas, if we are willing to leave port and venture deeper into the interior of the ocean, our actions may surprise the world. In fact, there is already a group of explorers who have been searching for various man-made wreckage at the bottom because of the huge potential value contained in it. This value usually belongs to those industries where wealth is acquired in a low-key manner, where only the holders understand and only they can trade with each other. For wreck salvage, the more civilian ships and the more famous the wreck, the greater its potential value.
The ocean is an extremely corrosive environment, and common building materials such as steel and wood can only exist in the ocean for a short period of time. Rare precious metals, natural gemstones, porcelain and other items have strong corrosion resistance and high value at the same time. Therefore, the greatest value of shipwreck salvage is the treasure excavated from the ruins, not the hull itself.
Recently, Chinese officials also announced that they had confirmed the coordinates of the seabed site of the Ming Dynasty merchant ships. Look at the neatly arranged items and look at the prices they have sold for Christie's to see the potential value. I believe that the "risk-taking" behavior of billionaires is not only to see the shipwreck in person, but also to see its value firsthand, whether they are willing to invest heavily in commercial salvage. If, as the media speculated, they were not trapped in the wreck due to self-detonation, but based on the experience of the OceanGate founder's previous dives, this also explains why the company has been able to continue to receive investment.
It is foreseeable that once China has submersibles capable of diving to depths of 10,000 meters, which are usually equipped with robotic arms, the United States will have similar technology, but will still need multiple submersibles to work together for salvage. The "treasures" under the sea will be left to the next generation of humans to discover the new "lost world".
