Bruh you have no idea about the costs. Doubt you have even tried running AI models on your own hardware. There are literally some models that will run on a decent smartphone. Not every LLM is ChatGPT that's enormous in size and resource consumption, and hidden behind a vail of closed source technology.
Also that trick isn't going to work just looking at a comment. Lemmy compresses whitespace because it uses Markdown. It only shows the extra lines when replying.
Can I ask you something? What did Machine Learning do to you? Did a robot kill your wife?
I am not talking about things like ChatGPT that rely more on raw compute and scaling than some other approaches and are hosted at massive data centers. I actually find their approach wasteful as well. I am talking about some of the open weights models that use a fraction of the resources for similar quality of output. According to some industry experts that will be the way forward anyway as purely making models bigger has limits and is hella expensive.
Another thing to bear in mind is that training a model is more resource intensive than using it, though that's also been worked on.
