Have you taken an electron microscope to trace each line for every CPU you use in production to know how it actually works?

No? Well perhaps, not needing to dig into how things work is a useful feature of a well designed system.

How many software systems are even 1% as battle tested as a "CPU"? Even the most well designed software system doesn't have the kind of test coverage of a hardware.

CPU's are complex and far from perfect, often shipping with hundreds of 'errata' at the design level plus a wide assortment of random manufacturing errors in each chip. So, there is software that has fewer bugs and better coverage than a modern CPU. ex: Grep

EX: Pages 19-73 with 2 to 4 errata per page for a single popular CPU design: http://download.intel.com/design/processor/specupdt/320836.p... And that's just limited to stuff Intel knows about.
