Who exactly are the people telling this writer that Uber will make transit obsolete? I live in a city where public transportation is very popular and have not once, ever heard this.
The reality is public transit use is surging in popularity. Public ridership is up 39% since 1995 (you know, when most people did not have internet or smartphones). Young people flock to cities with good public transit. And while I've never once heard someone say "Uber will make public transit obsolete", I have heard many people say they chose a city because it had good public transit.
