I did a lot of software development at EK. I know what it is like to debug millions of lines of code. OTOH, if it does not work the first time it is tried in the field, you have not done much testing. I had hundreds of test case scenarios that I went through after I made a change to the software I was working on. Same for film development when I did it.
Yes,we were blindsided several times with film products and software, but to me this product seems pretty poor at this stage of release. Which gets me back to the original point. They had the formulas and still can't do it? That is how hard restarting any analog product will be, and that is why I have said before how expensive and lengthy of a process it will be.
