But nobody can play that role in that active a chat for that long without occasionally contradicting himself, or his own eventual intentions, by sheer chance.
Also, I change my mind all the time.
One of the more obvious examples might well be discussions of infantry laser proliferation, where I have had, at various points, three very different answers and a lot of intermediate ones (most of this has been in the context of discussions with
@Chimeraguard about a potential Nodquest that would use a fair bit of the worldbuilding from mine)
A: Limited to no proliferation. The laser systems you use are going to be very too expensive, and very hard to both reverse engineer and make work reliably. So you have a situation where a unit of Serrice or Armali Commandos might have lasguns. The Destiny Ascension might get a laser defense system refit with your laser tech. But at the end of the day, if you find a room full of corpses with severe laser burns, it means that somebody very big and very scary has decided that something is going on that they really don't like.
B: Massive Proliferation. Your laser systems are relatively cheap and simple to reverse engineer, with lots of potential uses, and so lasguns, and more importantly lasgun attachments start showing up, simply because a laser gives you options that you don't have with a kinetic gun. So a lot of people end up either mixing it in a squad, or figuring out a way to carry both.
C: High/Low Mix. Instead of either extreme, the actual result is somewhat mixed. CBLs proliferate relatively quickly, but are far from universal, due to having a wide array of problems, while Infernium lasers face many of the same problems that produce the limited to no proliferation problems.
