The internet had a social contract. The reason people put effort into brain dumping good posts is because the internet was a global collaborative knowledge base for everybody.

Of course there were always capitalists who sought to privatize and profit from resources. The source materials were generally part of the big giant digital continuum of knowledge. For the parts that weren't there we're anarchists who sought to free that knowledge for anyone who wanted to access it.

AI is bringing about the end of all this as platforms are locking down everything. Old boards and forums had already been shuttering for years as social media was centralizing everything around a few platforms. Now those few platforms are being swallowed up by AI where the collective knowledge of humanity is being put behind paywalls. People no longer want to work directly for the profit of private companies.

Capitalists can only see dollar signs. They care not for the geological epoch scale forces of nature required to form petroleum. All that matters is can it all be sold and how quickly. Nor do they care for environmental damages they cause. In the same way the AI data mining do not care for the digital ecological disaster they are causing.

More over it's a thought terminating cliche when someone says, " existed before so why's it suddenly a problem?". It seems to be yet another out of the bag of rhetorical tricks that wipes the slate of discourse clean. As if all the arguments against it suddenly need to be explained as if none of it had any validity. Not only that but the OPs are often seemingly disingenuously naive. It provides the OP with a blank slate to continually "just ask questions". Where every response is "but why?" which forces their interlocutors to keep on elaborating in excruciating detail to the point where they give up trying to explain minutiae. Thus the OP can conclude by default they were correct that it's not a problem after all because they declare nobody has provided them with answers to their satisfaction.
