> Amazon literally didn't make profits for 10 years. Many other tech companies haven't made a cent yet, but investors are looking 5-10 years into the future for those.

Amazon went public in 1997. Boeing went public in 1962.

You get leeway as a young-ish public company, which will expire once you are an established player. How do you think markets are going to react if the bottom falls out of Amazon's business in 2055?
