An elf can accomplish difficult tasks in the blink of an eye, but in real life, there are few tasks that can be completed in such a short amount of time. However, in today's rapidly changing technological world, many tasks that used to take people a long time to complete, such as calculations, communication, transportation, production, and so on, can now be accomplished in a very short amount of time through high-tech means. This may suggest that people's lives are constantly becoming faster, more convenient, and more efficient.
