I don't think that the internet is currently dead ("dead" = "bot activity mistaken for human activity greatly surpassing genuinely human activity"), but that this is a real future concern.

One thing to take into account is that current bots suck major balls. Specially when it comes to utterance purpose, and for longer utterances; they fail the Turing test really hard, provided that the one asking "is this a bot or a human?" is able to interpret utterances based on nearby utterances and non-textual information around it. In other words if the internet was dead already we would've noticed it.

And someone might argue "ackshyually, there are more advanced bots that model language on pragmatic levels, you just don't know about them because it's all hidden!". Well, then you get a conspiracy "theory" with its typical appeal to ignorance, not something worth thinking about.
