Here we get the very crucial definition between "legal" and "moral".
It is not currently illegal to build a "database of weights and numbers" by crawling arts and images without permission, attribution or compensation, for the express purpose of creating similar works to replace the work of the artists whose artworks were used to train it and which they rely on to make a living.
That doesn't mean that it shouldn't be legislated.
Really not a fan of this "dying industry" talk in light of this.
