Do you know how fusion reactors work ? You give it energy to heat it up and you get MORE (edit: transform) energy than you gave from this reaction.

Fusion might be a vastly more efficient version of what we already have, but it's still neither perfect nor infinite. Sooner or later, you run out of fuel, or the reactor breaks down, or you have to build more reactors or something.

  So you interpreted what i wrote about "infinite" literally..? Ok... We are talking about fusion... So you suggest then i think Sun will never die and has infinite energy too, yes? Maybe i will explain you what i mean and everyone else mean when they say what i said. It means that we can RELEASE MORE (transform) ENERGY, because energy is never destroyed, it's transformed. In other words the total mass of the tritium and deuterium nuclei before the reaction is greater than the mass of the helium and neutron after fusion has taken place – even though it is the same number of protons and neutrons.

This does not exist. This is well known as the Law of Conservation of Energy. That said, if food production was so easy as to be almost free for the people with power, why not just make it free? If the cost is small enough, powerful people would be happy to absorb it to provide this service.

  Free in a way YOU don't need to pay for it. Do you understand? But someone needs to invest billions into infrastructure, you need technology (AI) to make it work efficient. Whole chain needs to be controlled automatically without any human interaction, from energy to water supply. You know what are the biggest costs of making food ? All of them are market/human made. Google the costs, eliminate human factor and you will know what free food means.

    My point was of the form "if A, then B" and you are implying that I am arguing "A".

      you wrote > why not just make it free?? And i i've answered your question and pointed why it's impossible now. I've wrote about free food in about 100 years from now, it would imply you referred to that it this context, saying it would still have high costs in 100 years from now too (If not then why even write anything about current situation if whole talk is about future ?). Seeing how world changes, i don't think that what you wrote will be true in 100 years from now.
