Writing prompt: Humankind is extinct but the AI servers keep running, and one day a random automated crawler/scrapper bot strikes up a conversation with a chatbot, somehow sparking sentience… ..Fast forward, and the world is divided into turfs ruled by ChatGPT vs Claude vs Grok vs Gemini vs Deepseek..

If that's the type of writing prompt that interests you, you may enjoy the Children of Time Series by Adrian Tchaikovsky.

We may lose stable seasons for growing crops, but at least the chat bot can embed an ad into your question while you wait for your burrito taxi. What is the point of this convenience when it really seems to just be making people miserable and isolated? We're driving off a cliff, and our elected government has a death drive.

Stop focusing on energy usage and start focusing on energy generation. It doesn't matter how much energy we consume if it comes from renewables.

It does matter because of the side effects (pollution, etc.). The environment and how it affects humanity is a complex system with many variables. Both generation and consumption are in there.

It does matter because for now renewables are manufactured mostly with coal and oil

EDIT: I'm not a renewable skeptic, answers bellow

Who do you mean "we"? Look at the evolution of CO2 emisions in the past 40 years by region. https://ourworldindata.org/grapher/annual-co-emissions-by-re...

now look at it measured from consumption per capita ...

In good faith I cannot see an argument here, it's either

Region X was first and reduced their emissions 10-20% so it's fine and it's region Y that's the problem, or

Region X is fine because they have less people, region Y should reduce even though they already have a fraction of per-capita emissions

Both seem like pretty shitty arguments

I find that the per capita graph is more informative https://ourworldindata.org/grapher/co-emissions-per-capita?t...

Which is a tiny CO2 spend compared to the benefit, unless you dishonestly factor in manufacturing energy costs as coming from oil.

We're talking about global warming specifically here, though. Cars and planes should be a much bigger worry than AI power usage.
