Have to disagree here as I don't subscribe to your analogy. GenAI can be considered a tool, yes, but it's less a "circular saw for workshops"-tool, and more a "microwave for kitchens"-tool... and I doubt microwaves led to higher quality content in aggregate.
I feel like a circular saw is a creator tool, while a microwave is mostly a finishing tool.
I take raw material and make something out of it with a circular saw, largely unrestrained by anything other than cost, skill, and material.
With a microwave, I make things hot so I can eat them.
Aside: Also, I wonder why that is? Why do we regard the microwave as "degenerate" compared to the oven? Why is baking seen as a calling while microwaving is, well, not? Is it the ease of the microwave makes the effort less impressive? Maybe it is that you can't achieve certain effects like browning? Is it because of it's 1970's association with "radiation" and tv dinners? Is it just cultural inertia?
