You admit that you don't know - and can't know - what "Intelligent Design" would be like. You admit that you don't know - and can't know - what the "Designer's" intentions would be. Therefore you don't know - and can't know - whether or not those intentions were achieved.
I would prefer to believe that we
don't currently (and collectively) know---the characteristics of the Designer yet we
can possibly and/or potentially know a Creator/Designer and may do so---some day!
In other words, I believe that we may not yet know and shall some day know the intentions of the Designer (God.)
