I went and watched the "fruit fly in Minecraft" vid, thank you for mentioning it. Pretty interesting! Especially from a video game design standpoint, it intrigues me because stuff like that could make for more nuanced simulations to formulate a game around. Though like you say, a model, not the real biological thing in motion. And from the sound of it, a lot missing in terms of how it works and why it's doing what it's doing and so on.
But yeah, I'm hoping we can, over time, reach a point where we have a better understanding of these things in general.
