In Japan, individuals who have attained high mastery in important performing arts and traditional crafts are often called "living national treasures." Around a hundred of these masters are recognized and subsidized for their contributions to preserving Japanese cultural heritage.

For these individuals, beyond public recognition, the goal is also to train successors. Performing arts like Noh, bunraku, and kabuki, as well as crafts such as lacquerware, papermaking, and bamboo weaving, must be passed down to future generations.

In the field of technology, we sometimes overlook older programming languages. Yet, we frequently call back retired developers when dealing with legacy programs written in COBOL, LISP, or Fortran. Some companies invest heavily in training new talent in these technologies.

While it may seem that traditional arts and older technologies are relics of the past, their preservation is crucial for future innovation. Even if your programming stack seems outdated, your skills are invaluable to many companies.
