I would go even further and say that that relationship between the two is weak, but also very peculiar: bad code can ruin a good product; but good code alone says very little, if anything at all, about the quality of a product.
It’s like mobile cameras, they reduced barrier of entry to photography, but you didn’t end up getting better photos necessarily. Instead you had more of them.
I like this idea, any new technology that empowers people simply increases volume, there's still an uncaptured element of strategy, design, and taste that doesn't improve with the tools themselves getting better.
