To state 'there is no interface' is disingenuous. Since the beginning, tools are a characteristic of human existence. Learning to use a scythe develops an 'interface'. This attitude, I submit is what is wrong with at least some of the ABI philosophy. Instead of a 'tool' the automatics are proposed to be nothing less than a superior 'pilot', whose purpose is to 'protect' the airplane. Inherent in this language is an 'attitude' (a human one) of 'supremacy'.
Who protects the a/c from the 'box'??? A 'cleaning lady' can fly this a/c!!!
"What's it doing now?"
For anyone to state 'there is no interface' merely underscores the root of the problem and his/her own lack of understanding. IMHO. I think too, that a loss of sensors as is demonstrable prior to if not a part of this accident, presents an arguably suitable example of the differences involved in manual flight and a litany of pre-programmed failures that cascade from a manageable defect into a very dangerous reluctance of the computers to perform at even a very basic level of expectation.
