They were called "unicorns" for a reason: No one really knew whether Silicon Valley's fabled billion-dollar valuations were real, or whether they were a mixture of delusion and financial engineering that would evaporate upon contact with harsh public-market realities.

Flashback: An influential paper in 2017 declared that, properly valued, most so-called unicorns were actually worth less than $1 billion. The paper downgraded Zoom's valuation to $500 million from $1 billion. Other unicorns imploded either before they went public (Theranos) or afterwards.
