"アイデアからプロトタイプを経て、何百万人もの人々が使用する製品にすることが大好きです"

Simplified Meaning:

When someone has a new idea, they first imagine how it could work and what it could look like. They then create an early model or example of this idea, called a prototype, to see if it works in real life. After testing and improving the prototype, they turn it into a real product that many people can use and enjoy. Think about how smartphones started. First, there was an idea to combine a phone, a computer, and a camera into one device. Engineers made a prototype to test how this combination could work. Over time, they fixed problems and added features. Finally, the smartphone was ready for millions of people to buy and use. The creator feels proud and happy that their idea has come to life and helps so many people. This quote shows the excitement and satisfaction of seeing something you thought of become something useful that others can enjoy. It’s about turning dreams into real things that make a difference in the world.
