AcidAUS writes: A little over a decade ago, just before the masses discovered the digital universe, the internet was a borderless new frontier: a terra nullius to be populated by individuals, groups and programmers as they saw fit. There were few rules and no boundaries. Freedom and open standards, sharing information for the greater good was the ethos. Today, the open internet we once knew is fracturing into a series of gated communities or fiefdoms controlled by giants like Apple, Google, Facebook, Amazon and to a lesser extent Microsoft. A billion-dollar battle conducted in walled cities where companies try to lock our consumption into their vision of the internet. It has left some lamenting the ''web we lost''.
Thus mathematics may be defined as the subject in which we never know
what we are talking about, nor whether what we are saying is true.
