it seems plausible that all new things are brought into existence unintentionally. that is, you tried to create something you imagined, but what you actually created was something else. certainly there are many examples of thinking about renewable energy that were completely wrong because they were based on presumptions that no longer hold, or in some cases were already wrong but in a nonobvious way

as my wife points out, we can't even imagine any of the things that do actually exist, only drastic simplifications thereof
