IS THIS FOR REAL???

Things have changed a lot since we first heard about something called the " internet ", " the US army is already using it" some said and others were talking about Windows that made the use of computers "user friendly". After 30 years from those statements we are living in a world where the biggest bank is Bitcoin with no actual cash, Uber is the largest taxi company with no vehicles, Facebook being the world's most popular media owner without creating any content, ALibaba is the world's most valuable retailer and has no inventory and Airbnb is the world's largest accommodation provider and owns no real estate.
