Well perhaps instead of insinuating motives,

I was thinking of my own motives in similar situations, sorry if you took it as a characterization of yours. I do see it could have been read that way.

you could share your thoughts about the actual stated reason?

I would suggest you e-mail your blueprint to a few of the posters here with the understanding they keep it to themselves. If even one long-term poster says "I've read Friedenbach's arguments and while they are confidential, I now agree that his estimate of the time to AI is actually pretty good," then I think your argument is starting to become persuasive.
