I had a similar reaction when I read the grandparent post. Could we not say the same about most retail shops and people who work at them? "Bah, why bother? In the long run, you will all be replaced with robot pickers in an Amazon warehouse." And yet, the retail "experience" continues to innovate / find / create experiences that people cannot have with pure online shopping.
Would you invest in either a bookstore or a big retail shop in a mall today?
The difference is that millions of people aren’t going to wake up one morning and say they want to start buying physical newspapers.
