I counter-suggest you google "nanobots" or probably more in general, "robots". let me know where they fit in the tree of life, and I will consider myself duly corrected and enlightened!
"I could casually acknowledge I didn't catch an oblique joke about a new way of viewing the natural world which I previously took for granted... but it's too late! To admit an oopsie would be anathema to my identity and social survival. In this desperate hour, I have no choice but to argue that it is categorically wrong to view cellular biology a form of nanotech or vice-versa, using the narrowest and most pedantic dictionary entries."
the responsibility of excusing an erroneous statement as "just a joke bro" probably belongs to the parent post of the post you were replying to, especially when I can't even figure out the jokes punch line lol but you're a good sport for pitching in. whats the punch line?
