Sorry, you are still 100% wrong. BTW, you're the one who brought up the analogy of a house, so I simply expanded on that for you. A better example would be a skyscraper. It would take an entire team of architects and engineers (and very expensive simulation software running on workstations) to design a modern skyscraper. It requires experts in fields ranging from materials (how much strength can a steel beam of a certain dimension and shape handle) all the way to aerodynamics engineers who wind tunnel test the final design. But in the end it's still assembled by ordinary trade workers (concrete, carpenters, plumbers and so on).
The "smart" work is done during the design phase. Once that's finished, the assembly is the easy part. Just like it is with processors where you could have a team of 1,000 engineers spend 2 years developing a processor whereas the fab (TSMC or Samsung) can ramp up production of said processor in a couple months with a fraction of the employees.
BTW, why are you talking about "theory"? Apples A7-9 processors are real items in production now. There's no theory behind them or the work it took to develop them or the fact they are more advanced than anything Samsung, Qualcomm or ARM is making. This is all fact.
