Assuming the question was

> How much time in day, do you think you spend reading what random people you dont know are saying?

Rather than "so what?", which I will come back to later: For me, probably several hours per day. It's not just here, or twitter/fb, though that's probably an hour by itself, it's also:

• Blog authors (parasocial relationships!) • Newspaper writers • Wikipedia editors • Review writers on Amazon, Google maps • Question and Answer writers on Stack Overflow • The first few comments under some Youtube videos • Comments sections on news stories

(Technically also book authors given the way you phrased that, but that's a different issue and current generation text generators make no difference there anyway).

Now assuming the question was "so what?", because that dovetails into the rest of your spiel:

The problem is not usefulness to you, it's "can this be used to automate convincing you?".

Make a half-decent sales pitch personalised at whoever for whatever: "Boiling eggs? Yeah that's easy, but I find organic is the best and well worth the cost", or "Oh, you're visiting Berlin? Yeah, I had a really great time at $insert_restaurant_here" or "Don't fall for the Lib Dems, they keep saying they can beat the Tories but look what happened when they got into power. That's why I vote $insert_uk_political_party_here". All personalised to just you, in the form of a friendly looking and natural response that probably seems more natural than any of my examples, because chatGPT is only reliably worse than domain experts and I'm not a domain expert in sales.

Also: You replied to me, and I'm a stranger, so we both know you engage with strangers on the internet, QED there's a place where you might get a bot trying to sell you a product or idea while pretending to be human.

Don't make the mistake of thinking the status quo is a good reference point here: Current advertising categorisation on social media sucks (easy way to find out: make GDPR request to FB or Twitter for all the data they have about you. They think I'm interested in languages I can't speak and politics of countries I don't live in).
