I'm sorry you're wrong. The more tasks we move to the digital world, the less carbon emissions will be emitted on net.
This is bad for human social cohesion imo, but objectively good for C02 levels if you claim to care about that.
Nothing physical we build for use cases in the digital world emits carbon on the scale of anything we build for use cases in the physical world.
And compute gets exponentially more efficient and uses less and less resources per unit of output over time. Combustion engines and humans in general don't get exponentially more efficient over time, for example.
You don't actually care about the thing you're pretending to care about if you're saying that AI is bad for the environment. It's probably bad for traditional social structures and institutions, but actually fantastic for the environment.
