When will the Foundation's dream of reaching $30 apiece materialize?

Its going to be a long journey for SLR then. New competitors cropping up as well.
You should have bought SLR when it was a fraction of a penny, maybe then you would be less eager to try and spread FUD. There's still a long way to go though as this is a 40 + year project so it's certainly not to late to get involved. As you pointed out SLR still has a lot of room for growth.
