Yet understanding the state of the tape and what it represents gets increasingly difficult the more abstract you get. Running a non-trivial programme in a Turing machine is as hard to inspect as disassembling one in a standard computer. The complexity does not lie on the general computing platform, but in the interpretation that we derive from its state - and, as long as the platform is turing complete, by definition, we will end up running inescrutable programs (because we can!).
