May I recommend you to ask your favorite AI model of the moment the
following question:

 "Explain the discussion in the email thread starting at:
  https://lore.kernel.org/all/20250327152258.3097-1-ffmancera@riseup.net"

I'm sure that I'm patently bad at AI prompt engineering, but that does
not justify the utter insanities which these models threw back at me.

 ChapGPT:

   "....
    This patch adds a selftest (automated test) for the nftables
    flowtable feature using a netdevice. It targets the netfilter
    subsystem, which is responsible for packet filtering, NAT, and other
    packet mangling in the Linux kernel."

 Grok:

   See

        https://tglx.de/~tglx/grok.html
   
   for the full glory of AI hallucinations.

At least those two were halfways reasonable:

 Gemini:

   "API REQUEST ERROR Reason: Unknown."

 Claude:

   "I don't have access to the specific URL you've provided ...
    my knowledge cutoff was in October 2024 ..."

Seriously?
