Up until now the tools being used aren't usually defining the end product. I don't mean library code or song samples, etc. where licensing comes into play. The tools I'm referring to, like an IDE, or art program, or even a paintbrush, might enhance the process of creation but they don't define the product.

With ML the output of the tool becomes a concrete part of the end product. So, surely the copyright ownership for the part of the product generated via ML is not held by the person using the tool. Which means you would have to license the ML generated part of your product from whoever produced the tool.

I have no legal expertise but it definitely feels like there is a dangerous trap in using these tools without that question being answered.
