The post is currently at -5. I bet if he had basically the same content but it was about some robot he just created the post would have a positive rank.

Creating a robot is easy. Everybody is born with the ability to create robots once they grow up so long as they can keep themselves alive and find a partner. In fact, not making robots is a harder task for many people and something that people fail at frequently, particularly if they lack education. If we started having people make posts every time someone made a robot we'd be overwhelmed with robot creation posts. Wait, no. Robots aren't the same as babies after all.

(I am approximately neutral regarding this kind of post. I reject this particular argument but not the preceding observation that such sharing can be beneficial to a community.)
