You could have said that about the dotcom bubble and be correct at that time. But the gold rush analogy fits very well for that scenario with the benefit of hindsight.
Any scenario including the current startup rush could be made to fit into either one of the options presented.
The reality is: a) currently we are not in an economic slump wrt startup funding b) there will be companies which will make it out of the gold rush looking like visionaries (ala Levis Jeans). c) there will be companies that have attracted significant capital which will go bust.
That is market economics with nothing unusual. The determining factor would be the % of the companies funded which will survive and thrive. I would bet towards a high percentage of busts than winners. And that doesn't make me a genius, i am just stating the obvious.
