I upvoted this without reading. For me sometimes the article is just the spark for a far more interesting set of comments that overshadow it. And it is really that I am voting for.
I upvoted after reading a large portion. I had commented previously that the use of Gaussian math was reductive, but I think the contrasting mathematics of the two types of inheritance is interesting to consider.
I've done the same. Discussions on some subjects are worth having and so I will sometimes upvote because I really want to hear what the HN crowd - who are by and large pretty smart and have interesting perspectives - have to say.
