Engineering isn't about perfect. It is about optimising to get the best practical result from availble resources in a finite time with finite input.
It was obvious as long as 5yrs ago that this project was too much for one man as as good as he may have been at designing for the simple reason that the technology was marching forward faster than one man could keep up. IIRC, JW was offered expert help that he declined. My investment was "only" £350 which is probably a lot less than some. My view remains that he probably never intended the project to be a scam but has effectively turned into one. I also suspect he's on the spectrum.
