Yeah, that's why we didn't have anything anyone could possibly consider as a "great product" until A/B testing existed as a methodology.

Or, you could, you know, try to understand your users without experimenting on them, like countless of others have managed to do before, and still shipped "great products".

I know this is a salty take, but reliance on A/B testing to design products is indicative of product deciders who don't know what they are doing and don't know what their product should be. It's like a chef saying, I want to make a pancake, but trying 50 different combinations of ingredients until one of them ends up being a pancake. If you have to test whether a product works / is good / is profitable, then you didn't know what you were doing in the first place.

Using A/B tests to safely deploy and test bug fixes and change requests? Totally different story.
