Don't take away my "for" loop from me.. It is the magical thing that brought me to computer science :)

Frankly, I can't tell anymore if the linked article is tongue in cheek. Enough HN for today.

"Google is replacing PageRank with RankBrain and when this is complete they won’t know why certain pages are offered as the best result" I'm not sure if this will always be true. I think that if we move toward a sort of neural network programming (1) we won't be able to "know why" in the sense that we can explain the functions, but will instead explain programs based on output from the layers and from the relationships between variables. For instance, deep dream is a way to understand how google's image classifier is "working" (2). It's super interesting that the classifier thinks that a human arm is part of a dumbbell, for instance. 1) Maybe something like this: http://web.mit.edu/~axch/www/art.pdf http://web.mit.edu/~axch/www/art.pdf. 2) http://googleresearch.blogspot.ch/2015/06/inceptionism-going-deeper-into-neural.html http://googleresearch.blogspot.ch/2015/06/inceptionism-going...

Could anyone explain to me whether this article is serious or sarcasm ? And if it is sarcastic what exactly is he mocking ? I guess that most HN readers would be unfamiliar the tools of the trade for big data and machine learning.

  Not serious, or maybe ha-ha-only-serious. See: http://philip.greenspun.com/humor/ai.text http://philip.greenspun.com/humor/ai.text The AI field has been a prolific source of hokey new terminology ... AI is about the same age as the rest of computing. ... If DOD spending on AI drops far enough, universities like Stanford, MIT and CMU may even find the integrity to rid themselves of scientifically embarassing, but formerly profitable, AI programs. The quality of CS faculties and budgets at universities across the country will continue to be diluted by the presence of large numbers of AI meatballs. -- Gary Martins (former RAND manager)
