Iumenta: A generic framework for animal digital twins

I have no idea why it needles me so much, and I will cathartically accept any downvotes, but why has the phrase “digital twin” entered our lexicon when it just means “model” or “simulation”? I’ve worked with incredibly smart AI engineers who talked about “building a digital twin” when they just meant “storing some data”. Maddening.

It generally means model running in parallel with the actual system. It is not just about being able to store data, but about being able to mirror (and sometimes predict/replicate) exactly what that system is doing.

In current software parlance, this is often used in stupidly trivial ways, but digital twins have a long and important history and function
