Been helped a lot by Brave Search's built in AI. Privacy search engines have always been somewhat more unreliable, and with Google searches going to crap now, sometimes that AI answer below the search answers my question or points me in the right direction when non of the results do. If AI's going to pollution the search results might as well use it to alleviate the mess it made.
Still would a loved to see DDG go the brave model and actually self host an open model instead of just embedding ChatGPT.
Edit: nevermind, see they offer both self hosted and ChatGPT3.
If you're talking extra plants for redundancy when power fluctuates, there's really now way to do that with renewables. Maybe giant battery stations, but that's about it.
