But if Steve went 'Hmm, I think I can maximise efficiency by just getting rid of all this green stuff altogether and turning the world into a factory', that would cause me some concerns.
I am ok with turning Earth into Coruscant if it actually works and doesn't lead to complete collapse in every sense of the phrase: institutional, societal, social, mental, engineering, environmental, pandemic, infestation, etc. God machine guy wants to get rid of the green? Tell him to grab some seed copies for research purposes first and I'll give him the green (heh) light.
People think, when they see me argue in favor of action to prevent climate change, that I like the environment. I don't. I need it, and I know the rest of humanity needs it, so I wish to preserve it in that respect; but honestly? I'd be happy to see it go. Really the only nature that ever appealed to me is the ant/arctic, but that's gonna be gone
long before any of the rest of the environment is on the chopping block. Plus, you know, you don't need life to have an arctic. It's the advantage I have over the tree-huggers: they need trees which are a extremely complex phenomenon dependent on a variety of complex environmental factors such as temperature, atmosphere, sun exposure, soil rich in organic compounds, etc. Snow needs only water, cold and atmosphere, and at least the water and cold are very, very abundant in the universe. Trees aren't.
Any halfway decent machine overlord could simultaneously protect the environment writ large and the human race with a number of non-genocidal strategies considering even I can think of them, but I guess that's the whole problem with machine overlords.
The problem is that you assume that they want or care about the environment, the human race, non-genocidal strategies... or your opinion about any of the above.
That's the problem with robot overlords.
My
current problem with robot overlords is that the fire alarm went off for the second time today, this time at 12:35. AM. First time it happened it was pinned on a suitemate (he was cooking, there was a smoke smell, it was probably him and he recognized that), but now I don't even think the Fire Department has a clue what happened. At least I met my neighbors upstairs for the first time.
Robot overlords need to work out the kinks first.
