I think there's two likely scenarios here:
1) My comment is only ever going to be read by computer programs and I'll probably get a response back from a computer program (see: ChatGPT/GPTs, character.ai, AI Studio, Replika, the countless "AI friend" services, etc)
2) My comment is posted in a more public setting that's inundated by computer programs, but also visible to other humans (e.g. a comment on a public FB post that computer programs read, but that other humans might also read and/or respond to)
#1 feels like current-gen one-on-one chatbots, but #2 is where I expect FB to end up eventually, using bots to keep conversations flowing and growing while humans interact here and there.
In either case, my answer is yes. It's still a conversation either way, isn't it?
