I agree with your first bullet point and that's a question for ethics and legal practitioners. As an end-user of a product (like ChaptGPT), we shouldn't have to worry (we can still be concerned) about labially of using a tool. This debate likely isn't going anywhere any time soon.
Your second bullet is a little more nuanced. Technology has ALWAYS been used to optimize process, remove humans, and have lower operating costs. Think how Disney animations were 50 years ago... thousands of animators. Now, a handful of animators with powerful technology. Excel replaced bookkeeping jobs, word processors replaces typists and stenographers, self check-out systems, ATMs, agriculture machines/autonomy, manufacturing robots, SaaS platforms... This list goes on. This isn't really all that different. Why employee hundreds of side quest writers when an AI infrastructure can write better, more dynamic, content on the fly? There will be places for this, like there are still a lot of those professions I mentioned above, just not as many as before.
Environmental concerns on using AI is an interesting one. I think we could have said this about all newer technology. Everyone now has a computer in their home, a refrigerator, etc... Not to go down that road again but there's precedence. Do I think it's good, no. However, the world is slowly shifting to renewable energy that is more concentrated with the location the energy is needed, keeping any impacts local and creating less risk/need on infrastructure for others. The energy resource needs are growing rapidly and won't slow down but so are the technologies and infrastructure that's helping generate the new energy. Ironically, AI will help reduce energy waste and optimize grids (like Tesla's autobidder software) where waste is rampant.
AI should continue to get better and is probably the worst it will ever be. This will only heighten this notion around AI taking away jobs and because of corpo greed (it IS about greed, but that's capitalism, in the US) but if history tells us anything, we will find ways to adapt and people will find new and interesting jobs that coincide with new technologies and tools. Even AI.
