The real question is, will machines compete with people for food ?

The sugar they use is glucose, and that is not so 'refined'.
sugar/fructose syrup, aka molasses when concentrated, is what you get when
extract sugar from beets or cane. This is done by crushing them in a mill
and then boiling them in water. This is a simplistic description of the
process but everything else has got to do with hygiene and increasing
yield. Check the price of refined sugar vs. fuel (mass for mass although
comparing by energy content would be better).
