-- documented facts -- considering that you've presented none that contribute to proving your point.
YOU: "We even did things manually in the 70's that COULD have been done with the LIMITED technologies they had then. Because of those LIMITATIONS."
Oh? Well how about you provide a couple-three examples of such "things"? What limited technologies were available then that were rejected specifically because of their limitations? Just what were those limitations that were to blame for producers' declining to take the higher tech path?
YOU: "Just because it COULD have been done with technology does not mean that it was the best way to do it AT THE TIME."
So what do you know about it? Just how common an occurrence has it been that the "old way" was able to stave off application of the higher tech way for more than a fleeting period of time, if at all?
Let's see what you know. Back up your BS.
