I never said anything about being worse, dumber, and definitely not slower. And keep in mind worse is subjective - if something doesn't require edge case handling or correctness, bugs can be tolerated etc, then something with those properties isn't worse is it?

I'm just saying that since there is such a wide range of experiences with the same tools, it's probably likely that developers vary on their evaluations of the output.

Okay, I certainly agree with you that different use cases can dictate different outcomes when using AI tooling. I would just encourage everyone who thinks similar to you to be cautious about assuming that someone who experiences a different result with these tools is less skilled or dealing with a less difficult use case - like one that has no edge cases or has greater tolerance for bugs. It's possible that this is the case, but it is just as possible that they have found a way to work with these tools that produces excellent output.
