> Would you go to a doctor that knows how to remove an appendix, but doesn't know how the circulatory system works? Would you go to a doctor who understands how to do a heart transplant, but doesn't understand the Navier-Stokes equations underlying how viscous fluids like blood behave? Would you trust your car to a person who doesn't understand friction at the level of interatomic forces? Would you seriously trust your life to an airline pilot who couldn't single-handedly design and build a plane at least as capable as the Ford Trimotor? People have always been specialized. Always always always. Even back before "specialization of labor" was officially invented, the people who lived in the Kalahari didn't know about hunting seals and people who lived in Polynesia couldn't hunt a buffalo or a bison to save their lives. There just isn't enough time, interest, or opportunity in one life to learn everything top-to-bottom. We're slowly improving the amount of opportunity, and you can fake an interest for a while, but increasing the amount of time is still a miserably slow process.
