You seem to have missed the "2017" part of "July 2017". The next halving is a year ahead of this.
There's a halving in 2020 after the one in 2016 (i.e. every 4 years on average). What are you talking about?
klestin knows its 2016.. he is rebutting Amph who seems to think the halving is july 2017(same time as 2mb gets activated)..
so Klestin is saying that the halving is happening a year ahead
(before) cores roadmap for 2mb.. not at the same time, to correct amph.
so lauda, putdown the Java book, and after you finish reading C++ for the first time, get a english dictionary.
