Please quote for me where he states he will continue this forever. Its you lovely people that keep making this estimations about what will happen "if things keep going the way they are".
I don't want to be a dick but Actually I could if I weren't typing this on a Kindle. He says he imagines this can go on for a very long time(he sees no end in sight) in the thread where we can ask Pirate questions (a day in the life of ...).
He told me personally this could go on as long as bitcoin was healthy.
