Response 1 (Joke): Thermodynamics assures me that the energy output will
be close to but slightly less than the energy input when the machine and
I are considered as a closed system. (Don't get any weird ideas.)
Response 2 (Almost serious): If the machine is considered to be the same
as tools, the human species has been using tools for over 50,000 years.
That is sustainable enough for me.
Response 3 (Serious): If the machines use solar power or the equivalent
in renewable energy for their use and full production cycle it would
require more than your _fiat_ to convince me that you are correct. I
would be interested in how you justify your statement. YOu may be able
to do so.
