I understand this sentiment but for the progress made to be of help to all of us will eventually require publication. If the preliminary results are published, others may be able and motivated to get involved and may have other ideas that lead to more progress. That's how science works. As you say, he's only one and he is elderly and mortal. The trailblazer needs to leave enough for others to follow.
I am not meaning to be critical of Ron. I am very thankful for his involvment and really feel for his situation. I just would love to see what he's finding published. It all comes down to money I guess.
