Everyone deserves companionship, it's just that chatbots don't provide it. What I worry about is people who don't want to have conversations with people at work, or go do a hobby with other people, etc. and use a chatbot as an alternative when it's just a parrot pretending to be a person but providing no actual interaction. A chatbot has no needs, tells no embarrassing stories, requires no compromise, makes no promises, does no favors. That's why I said it was candy, not McDonalds. They provide no nutrition but sure taste good.

That sounds similar to me like the argument against anti-depressants that it's "not real", and you're not actually better, you're just addressing symptoms, not the cause. But my experience is very clear: that's a huge improvement.

Clearly people have needs, clearly they feel chatbots satisfy those to some degree (otherwise they wouldn't use them). To those people, it's an improvement, I don't see how that's a negative.
