The people who hate "AI" are correctly understanding it as a political project, not simply a technology. Ali Alkhatib's definition here is clarifying in this regard: https://ali-alkhatib.com/blog/defining-ai
This entire brain dump of a blog post could be summed up in one famous sentence: Man is a political animal.
I never understand people who seem to have a need to grasp at such poorly written blogs for an understanding of today's affairs. Humans have really been remarkably consistent in their nature. The answer to your question has already been written, maybe even centuries ago by someone who thought about this a lot harder than you. Sometimes it feels like LLMs are so good simply because most people are far less interesting than they think they are. At some level humanity has been asking the same fundamental questions since the dawn of civilization. At a certain point what more does the average person have to say that we haven't already heard before?
I would agree that there is a political project happening in the AI space (and that it predates modern AI); I think it's worth giving that political project a distinct name, rather than conflating a term already widely used and understood very differently by normal people.
No. Obviously, what you do on your PC is inconsequential to the rest of society. But despite this, AI and its consequences in big tech have become so thoroughly linked because the entities that develop and profit off of AI use are so big and influential over the rest of us. The hobbyist space isn't what people even think about.
