I'm constantly tempted by the idealism of this experience, but when you factor in the performance of the models you have access to, and the cost of running them on-demand in a cloud, it's really just a fun hobby instead of a viable strategy to benefit your life. As the hardware continues to iterate at a rapid pace, anything you pick up second-hand will still deprecate at that pace, making any real investment in hardw…
I expect it will never change. In two years if there is a local option as good as GPT-5 there will be a much better cloud option and you'll have the same tradeoffs to make.
And my phone uses a tiny, tiny amount of power, comparatively, to do so.
CPU extensions and other improvements will make AI a simple, tiny task. Many of the improvements will come from robotics.
