I think as written, I’d say these words are more FUD (fear, uncertainty and doubt)
And I’ve been running servers for quite some time as well. SearXNG seems rock solid. And it’s tested. And when I had security issues in general, it was because we didn’t do timely updates. I haven’t really ever been affected by zero days in my hobby linux endeavours. Okay, we had a few nasty things in some more fundamental building blocks and sometimes people using slower distributions had been fine… But I don’t think it applies here. With these kinds of things, the latest stable release is your best bet. Not a previous version with bugs in it, which have been fixed since. And especially not an unmaintained project.
And with machine code, you got to keep track of what’s in the stack, CPU registers, … to make a sense of what the code and the next branch command does. It’s completely unalike processing human language. LLMs aren’t really set up to do it.
