Oh there's no denying the US military has ballooned to the size of a small to medium-sized country. That alone is a huge issue for me personally - I do agree with our country having any form of standing military but that precedent was abandoned 80 years ago.
I'm not sure how to properly compare the military of one country with the entirety of a country ~1/30th the size. On the surface it doesn't seem crazy for those to have similar budgets or resource use.
The comparison is in terms of energy use since at the end of the day that is the fundamental currency of all techno-industrial activity. The point is that the global machinery that is currently guiding civilizational progress is fundamentally anti-life. It constantly grows and subsumes whatever energy resources are accessible without any regard for negative externalities like pollution and environmental degradation. This is why I don't take AI alarmism seriously because the problem is not the AI, the problem is the organization of techno-industrial civilization and its focus on exponential growth.
It's only going to keep getting worse and the AI alarmism is not doing anything to address the actual root causes of the crisis. If anything, AI development might actually make things more sustainable by better allocating and managing natural resources so retarding AI progress is actually making things worse in the long run.
I think those really are separate concerns that should both be given more attention.
There's a strong correlation between GDP growth and oil use, that's a huge problem and one that likely can't be solved without fundamentally revisiting modern economic models.
AI poses it's own concerns though, everything from the alignment problem to the challenge of even having to define what consciousness even is. AI development won't inherently make allocating natural resources easier - with the wrong incentive model and lack of safety rails AI could find its own solution to preserving natural resources that may not work out so well for us humans.
The current model is already destructive and most of the market is managed by artificial agents. Schwab will give you a roboadvisor to manage your retirement account so AI is already managing large chunks of the financial markets. Letting AI manage not just the financial aspects but things like farmland is an obvious extension of the same principle and since AIs can notice more patterns it's going to become basically a necessity because global warming is going to make large parts of existing farmlands unmanageable. Floods and droughts are becoming more common and humans are very bad at figuring out the weather so there will be an AI agent monitoring weather patterns and allocating seeds to various plots of land to maximize yields.
Bill Gates has bought up a bunch of farmland and I am certain he will use AI to manage them because manual allocation will be too inefficient[1].
