I'll start with an analogy: I have several friends who are chefs. They own their restaurants but they still get in their kitchens several times a week and "work the line" because, beyond their restaurants being businesses, they also enjoy the art/craft of cooking.

They've learned some valuable information about successful cooking that makes them fast, efficient and, by extension, profitable.
To help them in their work they've learned to choose the right tools for each process. And few tools are as important to a chef as their collection of knives. They have paring knives for fine work, they have big cleavers for heavy duty chopping, and they have assorted serrated and non-serrated utility knives for chopping and filleting and slicing. But, here's the important thing! They don't do every task with one magic, perfect knife.
It just doesn't work that way. They select the knife that will work best for each kind of work they do. The could do okay with a few well chosen knives but it would not be as much fun and it would just make their work take more time. Some dishes might suffer from the relative mismatch of tools and ingredients... Fingers might get nicked. So, selecting the right tool = good.

Well, there seems to be a pervasive mythology in photography at large that somewhere, in some mythical camera store out there, exists a perfectly sorted camera for every user. One all purpose machine that is a perfect fit for everything the photographer might ever want to do. One need only find their own mythical
