I can attest to the accuracy of what was conveyed in this interview. I wrote my first program in 1971 and have written over 1 million lines of source code since. I only mention this background to provide a credible witness to what can be done by a programmer which would remain a mystery to the end-user. I personally do not trust technology, especially smart phones… Just sayin’.
The interview has technical jargon that the average person will not understand, but don’t let that keep you from seeing the big picture.
