It is very sad that they won&#x27;t open up, and very short-sighted as well.  I&#x27;m sure Whitney and KX are perfectly happy with their millions, but they are sitting on one of the most impressive software achievements around and refusing to share it.  It&#x27;s not even like it would cost them.  First Derivatives could grow a consulting empire.  I mean, look at open-source MongoDB. It is a piece of shit, and it is valued at $1.4B.  KDB is finest thing I have ever used, and First Derivatives purchased a controlling stake in KX for £36.0M.  It makes no sense.<p>Maybe kOS will be open-source.  Maybe it will be the big one, Arthur&#x27;s chance to change the course of software development history.
