Airbnb or Uber are not really tech companies. They are business companies with a WebApp required as part of the execution. They didn't invent anything on the technical level, they brought some business ideas to existing tech (I mean Airbnb is literally a website with a DB)<p>In the same way that United is not a tech company, but they have a website that accepts reservation.<p>Tech companies create new Tech as part of their lifecycle: Intel, AMD, Google, etc etc. They create new Tech that didn't exist before, and this is core to their product.<p>I get that Silicon Valley shifted from Real tech 20 years ago to Futile WebApps that deliver pizzas faster, but it makes me sad that the new definition of tech shifted so much to pure business.
