are Roshar and Scadrial experiencing some kind of convergent evolution ? What could this mean for the future ?

[Jult]

We hit on a couple of these in @Cosmer's Will the Real Survivor Please Stand Up? topic as well. It is pretty curious. So, what would a convergent evolution of some kind mean for the future? Well, it seems like Scadrial has a headstart. So, maybe we could use Scadrial to predict some of Roshar's future?

• The emergence of Twinborns, for instance, is something I could see mirrored on Roshar. Perhaps an expansion on how Venli is holding both a voidspren and a normal spren in her gemheart? Or just more Shallan style double-bonds?
• Fabrials already pretty obviously mirror Medallions, but we know both are going to progress in major ways
  • Speaking of technological advancements, electricity is already becoming a normal thing on Scadrial and it would solve several problems if Roshar could do the same
• Advancements in Hemalurgy have already been foreshadowed on both planets, but Scadrial will likely get there first since they've had it longer
• Aimians seem to be a good mirror to Kandra, but I can't see them devoting themselves to Retribution like the Kandra did for Harmony
• I wonder if half-singers would function similarly to the Koloss-blooded. As in the way Koloss-blooded can choose to become full Koloss by accepting spikes at a certain age. Maybe Singer-blooded can choose to go full Singer by accepting a spren at a certain age? Doesn't seem right to me, but what do I know?
• The only other Era 2 Scadrial thing that comes to mind is the Malwish. But I think we'd know by now if there was a secret second continent somewhere on Roshar

Regarding the Singer-Blooded vs. Koloss Blooded, we already have horneaters, who, as far as I am aware, were originally offspring of Singers and Humans, also arent Koloss Blooded just the children of tow  Koloss? And not Koloss Human Hybrids

Horneaters and Herdazians are both suspected of being at least partially Singer, yes. But they seem very distantly related (likely they haven't had any actual Singers in their bloodlines since before the Recreance). I imagine the immediate offspring of a human and a Singer would be quite different.

Both actually. Tarson, for example, has one human parent and one Koloss. I believe the term is used for anyone with Koloss blood (even full-blooded) who is either too young to receive their spikes or chose not to ever receive them.
