Sure the free market will govern most options, not all will be successful, I am skeptical mainly because of the lack of attention to the downside risks.
That is where I am at also, trying to understand the downsides and risks.
What the cheerleaders miss is that by continuing to ignore the downsides and risks, or to claim that they do not exist, or to suggest that they are unimportant because the upside is so huge....the message is that any problems will not be solved.
Most of us understand the incredible potential of the offering.
However if this thread were any indication...there is very little confidence that there are any adults in the room with them, shepherding this development effort to that potential success by looking out for the pitfalls.
