Because we're not curating a culture of this, certainly not in tech. On HN, we celebrate AI output more than human work, in the sense that many stories make it to the top only because a project was done with AI. There are several on the front page right now. When people point out that they prefer human output, they usually get comments about getting on with the times. In threads about mathematics, most commenters root for the destruction of that community. And on and on.

Other communities are more protective of human output. For example, you'll get chased with pitchforks from the watercolor community if you post anything that smells of AI. But in tech, the number of people you can impress with human creativity has diminished by orders of magnitude.
