It's an innovative market, which means people are trying a lot of things. Given that, there's always going to be an "oversupply" of things that don't work or don't solve a problem anyone really cares about. The only time you don't see such an oversupply is in a market where nobody is trying anything new... such as automobiles from about 1960-1970 until the 2000s (hybrids). No errors means no trial is happening.
