In fact they were only saved because he had secured financing mere months before the collapse, had that not happened Amazon would be listed among the likes of Pets.com.
But, the 60-minutes reporter didn't justify his claims based on risk or on math. He was skeptical because Sears is huge, and to him it was laughable [and yes, he did literally laugh many times in that interview] that Amazon can someday be worth more than Sears. To him it was "messed up", and a sign of things wrong with the world
Two years later it was trading at $10, and didn’t recover until 2007.
The interviewer was right; Amazon was over valued.
The reporter is supposed to be an expert in this field. That's why 60 minutes hired him, instead of someone else, for the job. I am sure there was no shortage of applicants who wanted this job.
Why couldn't he be more open-minded and supportive of a startup like Amazon? Instead of constantly laughing at Amazon and Jeff Bezos (like his choice of cars)
So why be a snob? As you said, no one knows what will happen. Why laugh at the little guy? You don't know what's going to happen
Being open minded and supportive is probably a stretch when something sounds so outrageous that you simply can't believe it's anchored to reality in any way. I assume this is how it felt back then. Probably there were situations where you yourself became derisive of certain things you simply couldn't conceive could be different only to be proven wrong some time later.
