Gianluca Bontempi is not really convinced that one more blog on data science is absolutely needed. At the same time, he has often the feeling that something is not said in the overwhelming literature on this topic or, more simply,  lost in the assumptions of the domain experts. Also, as he is getting older and lazier, he is more and more convinced that some interesting considerations about intelligence and machines demand nowadays too much effort (and delay) to be translated into conventional scientific outcomes (e.g. publication), also given the overspecializations of scientific communities (or parishes). To him, this blog appears as a convenient shortcut to make some free thinking considerations without being forced to run the gauntlet of a reviewing process.
