I just wanna say THANK YOU VERY MUCH for this thread and everything good
which will undoubtfully arise from it. You rock.

And for those unware I would just like to point out
https://en.wikipedia.org/wiki/Intel_ME#Hardware which explains that on
modern Intel CPUs, there's another 386 CPU inside the CPU, running Minix,
so that "The ME has its own MAC and IP address for the out-of-band interface,
with direct access to the Ethernet controller; one portion of the Ethernet
traffic is diverted to the ME even before reaching the host's operating system".

My point is not, that other CPUs don't have this problem, but rather that
there's a lot of 'invisible' firmware on any modern computer, starting with
the CPU but going down all the way to the battery, screen, mouse and keyboard.

So this thread is (roughly guesstimated) only about 10-23% of the firmware
running on your computer, while today (as opposed to 1993) most of this
firmware *can* be updated.

IMO firmware is (sadly or not) somewhat out of scope for Debian. Even though,
or maybe precisely because hardware *is* software nowadays.


So, I'll say it again: many thanks to everyone involved in improving
running Debian on modern computers.

And huge thanks to those working on free and open hardware too.
