I think we have some notion of a proto-grammar or ability to linguistically conceptualize, probably at the level of some primordial conceptual units that are more fundamental than language, thoughts and ideas in the concrete forms we generally understand them to have.

I think it's like Chomsky said, that we don't learn this infrastructure for understanding language any more than a bird "learns" their feathers. But I might be losing track of what you're suggesting is software in the metaphor. I think I'm broadly on board with your characterization of DNA, the mind and memes generally though.
