Umm...80% or more of code running businesses today is not hosted on a webserver.
All the things he mentions, including the web, are a thin veneer of cool on a core of mundane.
Things like your paycheck, 401k, benefits, scheduling, purchasing, sales, repair, shipping, renting, inventory, routing, tracking, etc. etc. etc. are all done on fairly large computers running dull code like COBOL and even FORTRAN. They may have Web interfaces built with all these wizbang thingies, but the real work happens in legacy systems that are solid as a rock because they don't change technologies every three years to something cooler than what they have now.
