Maybe not an individual prompt, but with how many prompts are made for stupid stuff every day, it will stack up to quite a lot of CO2 in the long run.
Not denying the training of AI is demanding way more energy, but that doesn't really matter as both the action of manufacturing, training and millions of people using AI amounts to the same bleak picture long term.
Considering how the discussion about environmental protection has only just started to be taken seriously and here they come and dump this newest bomb on humanity, it is absolutely devastating that AI has been allowed to run rampant everywhere.
According to this article, 500.000 AI prompts amounts to the same CO2 outlet as a
round-trip flight from London to New York.
I don't know how many times a day 500.000 AI prompts are reached, but I'm sure it is more than twice or even thrice. As time moves on it will be much more than that. It will probably outdo the number of actual flights between London and New York in a day. Every day. It will probably also catch up to whatever energy cost it took to train the AI in the first place and surpass it.
Because you know. People need their memes and fake movies and AI therapist chats and meal suggestions and history lessons and a couple of iterations on that book report they can't be fucked to write. One person can easily end up prompting hundreds of times in a day without even thinking about it. And if everybody starts using AI to think for them at work and at home, it'll end up being many, many, many flights back and forth between London and New York every day.
