Newbies often would rather just take the expert's opinion.

The expert might say, "you can do any of these five options!"

But the newbie says, "I don't even know what the tradeoffs are, or how to even make this decision, just tell me your recommendation and I'll do that."

Making good, opinionated, balanced calls is hard and requires deep expertise.

It requires the calibrated curatorial ability to cut with confidence and to understand the implications of the decision, to not do it naively.

To cut you have to understand the tradeoffs that are only obvious with experience.

These cuts then make it wildly easier for beginners; instead of time swirling and lost trying to decide among other options, there isn't even a decision to make.

This is one of the reasons I love Golang as a language.
