"""
ACPI comes from an era when the operating system was proprietary and
couldn’t be changed by the hardware manufacturer.
We don’t live in that era any more.
However, we DO live in an era where any firmware code running on your phone,
tablet, PC, TV, wifi router, washing machine, server, or the server running
the cloud your SAAS app is running on, is a threat vector against you.
[...]
Arguing for ACPI on your next-generation device is arguing for a trojan horse
of monumental proportions to be installed in your living room and in your
data centre. I’ve been to Troy, there is not much left.
