OK... Using that approach I would assume that software has also lost money over the entirety of its existence. Perhaps not completely "untrue", but a silly way of looking at it and not what anyone would assume you were talking about.
Not sure why it's a silly way of looking at an industry's long term performance. It shows that, while occasional profits are made, the industry is prone to brutal, un-differentiated price competition...
So you're saying you believe the Delta CEO when he says "Industry May Never Again Lose Money"? [1] Considering the above, I'd be skeptical they're experiencing more than temporary, cyclical profitability.

It's all rather irrelevant. I don't know if software has actually been a net loss, but I know that looking at failed airlines and extrapolating out to the successful ones is silly.
