Just like the seemingly ordinary FR4 PCB boards in many electronic devices, they may be inconspicuous, but they are crucial for the stable operation of the system. After experiencing the lessons of using complex solutions that frequently failed, I believe that doing simple things well is more valuable than blindly pursuing innovation. Good products often hide complexity behind the scenes, leaving users with stability and peace of mind."}
