The first thing you can do is not buy anything that makes the tech billionaires more money. All they care about is money: don't give them any if you can help it.
get off of facebook (easy). don't buy tesla or use starlink (easy). don't buy on amazon (difficult but doable). Don't upgrade your iphone, and don't buy new apple products (moderate). Don't use CHATGPT (easy).
Use Linux and open source software. Contribute to open source projects. Buy hardware second hand. Use non corporate social media. Buy local. Get your stuff fixed instead of throwing it away. Avoid data harvesting where possible.
Getting off Amazon was easier than I thought. Has been years now, and I only needed to order through a friend once, when I needed a specialty item I could find nowhere else. Most small shops have comfortable checkout systems now and short delivery times. And there's eBay, which afaik takes a smaller cut from third parties than Amazon.
I'd add not using Amazon Prime, Amazon Web Services and other Amazon services. Not using X, being critical of SpaceX. Also, stop advertising these things, stop telling your friends about them, maybe even stop talking about them altogether. I think for some strange reason sometimes bad press is better than no press.
or use starlink I don't know if I'd call that easy for some people in very remote areas. Easy for me, easy for you, but not necessarily easy in some cases. Here's hoping a good competitor can get to those places.
Any relatively new gaming PC from the last, what, 4? Years has enough power to run local LLMs. Maybe not the ginormous 70GB behemoth models, but the toned down ones are pretty damn good and if you don't mind waiting a few seconds while it thinks, you can run it completely locally as much as you want, and whenever you want.
You would benefit from it with some GPU offloading, this would considerably accelerate the speed of the answers. But you only need enough RAM to load the model at the bare minimum.
