is that there aren’t any.
That’s precisely what makes them so interesting. The null set. The impossibility of it.
A unicorn is not a black swan, which is a rare bird that proves a point. A unicorn is by its very nature, impossible. That’s actually not a problem. That’s the entire point. That there’s something unavailable.
Instead of aspiring to unicorn status, a pipe dream which is simply a place to hide, we can instead decide to do something useful (and possible) instead.
It’s more challenging to set your sights on something that’s possible. More useful, too.
[HT to Michael, for a tangential unicorn riff. He points out that now that so many companies are called ‘unicorns’, the term is meaningless, a lazy trope used by some in business media who eagerly substitute lazy tropes for insightful analysis and interesting assertions.]
