Answer:
The detail that best shapes the idea that the Japanese art of boat building can be lost to future generations can be seen in the lines:
"Even in Japan, where traditional crafts are revered, this system is too grueling, too much at odds with modern life, to survive. It is no wonder, then, that as a generation of Japanese boatwrights has retired, their knowledge has retired with them. "
Explanation:
The text above shows how the Japanese art of boat building is carried out through a slow process, with years of study and learning, where it is necessary to have a lot of patience and be very observant to learn. This passivity and slowness that the Japanese art of boat building presents, does not match the modern and dynamic world in which we live today. This made less people interested in this art, for this reason, when a boat builder retires, he doesn't leave anyone in his place and all his work and knowledge retires too. Over time, all boat builders will be retired, which will cause this art to be lost through the generations.
