Yes, I understand the theory. But you've assumed the very thing I'm questioning: "when the killer product does arrive". Killer products for particular hyped tech visions frequently don't arrive, at least in the necessary window for a given wave of investment. We don't have jetpacks. There were people who invested in flying cars throughout the 20th century; Are they now "become to dominate leader"? Or look at Motorola's Iridium. Zepplins, wireless power transmission, vacations to the moon. All commonplace in sci-fi, and all things people have invested in. The killer product never arrived. Facebook is doing this because Mark Zuckerberg wants to remain rich and relevant. But just because his ego can't conceive of his company becoming irrelevant doesn't mean we have to play along.
