Those people are dead wrong on both counts. Cooking meals benefits more from precision than they claim (if you want reproducible results you best be measuring!), and baking does not require as much precision as they claim (I estimate ingredients all the time when baking and my bakes come out great).

There's a lot of mysticism around baking online, but in truth it's very easy. Just follow the recipe and you'll be ok. You don't need to carefully weigh ingredients and stuff like people say.

Cooking is art, baking is a very easy science (weight things and check the temperature), pastry is another thing. That requires talent, experience and a lucky star.

Baking bread is fun because its not science. It had guidelines but thats it

if there was no room for "errors", how is it possible that there are tens of thousands of different bread and cookie recipes and stuff like that?
