Incredibly useful for some definition of incredibly useful. What I see:

- I now regularly receive AI-written spam emails (marketing pitches, "vulnerability reports").

- I was receiving AI-written garbage quality pull requests. It got so annoying I closed pull requests on my project's repo.

- When I try to contact some company's customer support these days there's a good chance I will be fed slop by an agent posing as a customer support person, this is absolutely infuriating.

- When I search for information on the internet, for certain queries, 90% of the results is slop.

- AI crawlers are DDoSing websites.

- The already mentioned things – hardware getting more expensive, climate impact, unethically sourced training data.
