We are machines. As reflective machines we want to be well-honed, highly skilled and knowledgeable. We want to live in strong families and strong societies, ones that help us build things and explore more things, and that help us have more pleasures, probably both base and more refined.
There is no reason to call the capacities we arrive at virtuous. The definition and connotation of the word simply means it needs to be abandoned. We understand the well-honed nature of the machines we can be. What it means to be skillful or not skillful. What it means for a machine to be able to perform an activity to a greater or lesser extent. Why we would take machine-like activity and describe its functioning, and then tack on the idea that a certain threshold performance of the machine is virtuous, just seems flat out unnecessary.
I am also a strong moral anti-realist, meaning there is no such things as morality (and hence ethics in many configurations). The language of morality or ethics is not the best descriptive language in the end, and I argue that it will not help us achieve the best societies and worlds, mainly because of its descriptive muddling. We want to build robust selves and a robust social world, probably because it will lead to even more robust selves and burgeoning worlds.
