Time for some REAL Dehaka posting and my interpretation of one of his most infamous quotes.
"Their tools stay the same. I collect. I change."
A very poignant quote about not just the primals but zerg attitude in general to the terrans and protoss and the difference in how the zerg developed. When I see people talk about this quote, it's seen as a great example of the limits of the primal ideology, and their inability to understand how technology could outpace their evolution.
I think this is a bit flawed though, one point from a silly gameplay perspective, and another from a more deep and thoughtful analysis on the primal zerg's perception of the world. To quickly touch on the first, I think it's funny considering in game (And in lore) primal zerg (And the zerg in general) go toe to toe with terran/protoss machines all the time and match up just fine against them, so really they aren't necessarily wrong lol.
But as for the character analysis, I find it interesting how Dehaka draws a distinction between the tools and the person using them. Common sense usually means that if you see a person using a tool, that's an extension of the person and not some sort of partnership between two separate entities. Even very sophisticated tools, both in real life and in the future of Starcraft with things like advanced computer systems and space stations (I know I'm really stretching the definition of a tool but stay with me) aren't seen as an independent factor in the work. They're a means to an end and their value comes from how they enhance a person or people's abilities. A shovel will never be a sword, but unless you're playing Shovel Knight it's not expected to be, whoever is using it will simply switch their tool.
Primal zerg however have a totally different point of view. They are the tool, to a pack leader their pack is the equivalent of a selection of tools. Every individual is that, an individual. Each one is its own entity contributing, and for specifically a pack leader like Dehaka who values change and adaptability, true specialization renders them useless. Dehaka cannot see the value in having an unchanging tool, not because he thinks "Terran tanks are crappy" to which everybody rebuts "They'll make a better tank," which I believe is the usual interpretation of a quote. Dehaka instead sees that "The tank will never be anything but a tank." It can be the best tank possible, but fundamentally it cannot change what it is, and so it is a failure since what if you don't need a tank? For a primal zerg, they could simply adapt to whatever the new situation is, but the tool will stay the same and be useless. Why would a primal zerg ever want to use the equivalent of many dead ends when they constantly change to whatever their environment demands? They could be anything, and have no obligation to remain stuck, and I think this philosophy can be seen even in the gameplay of the zerg somewhat. Hydralisks and Lurkers for instance, while not a perfect representation, do capture the general idea of the zerg adapting themselves to respond to new situations.
I don't know, I hope some of it at least makes sense. This was mostly spurred on by some conversation on the starcraft reddit about character quotes and me mulling over this one for a bit in my head, and now I finally have an outlet for my thoughts lol.
