How do we actually define a company's true category?

Consider Amazon—is it just a bookstore, or has it evolved into something fundamentally different? Same question with Tesla. For years, skeptics dismissed its valuation as absurd. Sure, it looked insane if you were valuing it as a traditional automaker. But what if you're looking at the only publicly traded pure-play vehicle in a completely different market segment?

The narrative is shifting. Investors are finally starting to recognize that these aren't one-dimensional businesses anymore. They're platforms. Ecosystems. And that changes everything about how we should approach valuation.
