Reid, isn't best practice is to write SQL Query instead of checking whether Query will fold or not?

What is so special about query folding? Why we should care about it? Incremental refresh works without query folding. Some folks say, it is quicker. But how can "Select * from Table1" writen by me (which does not fold) be slower than same thing written by the engine?
