"エンジニアはエンジニアのために働きます。一方の好奇心が他方の技術に繋がり、最終的に妥協なく本当に役立つ製品が生まれる、再帰的なプロセスです。"

Simplified Meaning:

Engineers often design things for other engineers to use, and this creates a cycle. When one engineer gets curious and creates something new, another engineer can use that new tool to build even better things. For example, one engineer might invent a new kind of computer chip, and then another engineer can use that chip to create faster computers. This back-and-forth process of creating and improving leads to high-quality final products. The quote suggests that when engineers focus on solving problems for each other, the end results are very robust and effective. People can take this idea to heart by working together and using each other's strengths to make the best possible outcomes in any project.
