I think anything with text generation is fine. Your multiple Google searches are highly likely to eat more resources than that. Also, fuck Google, use Ecosia. But when I suspect an answer isn't one quick search away, I happily rather use Le Chat for answers, than give Reddit traffic, or have to wade through the shite that is Fandom, Wikia or whatever. Not to mention using AI helps me get past the issue of having to check multiple sites for an answer, just to find that the answer is "Google it" or "Nvm, solved it". Some of you fuckers did this.
However people need to understand that an AI is exactly as fallible as any person. Yes, it has access and capability to handle way more data but between trying to please you and just it getting it's wires crossed, it's going to make mistakes. YOU need to be able to assess the accuracy of the output. The more important the topic, the more careful you need to be and always assume that the possibility of error is there no matter how hard you try - JUST LIKE WITH ANY BIT OF INFORMATION. I see so many people cite academic articles like they prove whatever claim they are making, just to see that the study in question was funded by The Company That Wants to Prove The Claim and sample size was 3 people who work for The Company That Wants to Prove The Claim. At least AI has a small chance of pointing the issue out if YOU yourself tell it to be critical - and I actually suspect this is part of the reason some people hate AI. They don't like that it absolutely can be more intellectually rigorous than a person with an emotional investment in whatever they want to be true. Yes, you can have an AI asspat your grandest delusions but if you actually try to get it to be critical, it will be. You can use a hammer to hit people, or you can use it on a nail as intended (and how many times you hit your own fingers is on you, not the hammer).
I would draw a line on artwork, videos, music. While I'm not going to crucify actual artists using AI assistance to take out some tedium from a project, I still wouldn't encourage it. Stolen artwork to train AI is one thing and the environmental impact is VASTLY greater than just text. Generating one AI image can use as much energy as even a 1,000 text responses. I would also really like to be able to completely opt out of AI slop in media sites. I fucking hate that Soundcloud allows it.
And a last point on AI text responses: if you saw the rise of alt-right and the anti-vaxx stuff, you probably are familiar with gish galloping and Brandolini's Law. If not, you really fucking should be. AI can make it so much easier to debunk misinformation. YES it can make it easier to perpetuate too but this is where we see the AI weapons race. Bad actors can AND WILL use AI to fill any void with their rhetoric. If you value truth and facts and want to prevent misinformation from spreading you are gimping yourself if you're not using AI.
