That's actually just where I stopped, recently just met them. More recently met "the Betrayer" wondering about his identity, I swear that series is so storming creepy and insidious and then randomly hilariously absurd in the best way, but I need a break I think! The way Stephenson writes is mezmerizing, but difficult and very tiring to read after awhile. Very much enjoying the focus on just a few characters and Sanderson's more approachable style right now though.
Dalinar later explains this a little more, that what he thinks its saying is that the lighteyes, being so powerful should be the protectors of the darkeyes and dedicate their lives like the Radiants did to more protect and serve, but not to be "servants" below that of the darkeyes.
First, I'm glad that Kaladin is still a darkeyes when he's not surgebinding or whatnot. I feel like he's the common-man hero Roshar deserves and it'd honestly be kind of depressing I think if he just turned into a lighteyes.
Second replaying to nervousnerd, I don't think lighteyes are the rulers because people looked up to the Radiants 4500 years ago.
Like I was saying earlier. Imagine you took a big population of darkeyed Alethi, wiped their memory and moved them to another place for a fresh start. They no longer have any knowledge or lighteyes vs darkeyes, the heralds, radiants, shardblades, etc. You let them do their thing, they develop their own society anew, and then you give 100 of them shardplate and shardblades... Those shardbearers become lighteyes and become hugely powerful. Naturally most of the shardbearers would take over and this cycle would just start again. They'd pass down the blades or forfeit them when they were defeated. Naturally these lighteyes would probably form royal marriages, and have children with other powerful lighteyed allies. In less than a hundred years you'd probably have another society where lighteyes would become the aristocracy and darkeyes would again be the peasantry, hoping one day to win a shardblade and cast of their inferior darkeye racial identifiers and become a superior lighteyes. to me this is how i think of roshar and it seems to me that no amount of cultural enlightenment would be able to counteract the prejudices that this would continue to be created in peoples minds as a result of this system. this is also why I kind of meant that this is oddly, in some ways, more depressing than the deep dark fantasy of malazan (where genocides seem like they're a dime a dozen).
