Defrost, now assuming there did not exist an interpretation that makes that original comment sensible - and really, I can think of one (it is vague and does not matter now) -, now consider the several possible reasons one may say instances of what you call «silly things», starting from a very personal sense of humour to very possible, "very personal other states". Automation being just a very limited sector in the realm of possibilities. Now see the image of somebody calling a "bot" somebody else who may, in an important range of cases, struggling for their own reasons - a few of them also common to all of us, unless for example some Benjamin Button's syndrome had you born fully adult.

I myself had been called "a bot" in this pages for having written very, very valid, I grant you, pieces of data and instances of reasoning that some in the public could not understand and dismissed. Even the style I used for this post I can already tell you will trigger a "must be a bot" in some readers. "Avoidable".

Take the seconds required to make a list of why people may «say[] silly things», and see why it is not a good idea to call them a bot. If you really cannot figure out some trivial possibilities, I may mention some among us that could create Operating Systems and yet "struggled".

Edit (an addition):

Paradoxically, if you could not understand, in some "Voight-Kampff test" scenario, why it would be offensive to call a bot e.g. some "Nietzsche" behind the curtains, guess who the Bayesian needle would incline to suspect as a bot.
