We are still developing the fire so uniquely, there's no reason to go look for another match.
PLUS ... y'STILL gutt'a have a shovel to dig the dirt to put the fire out.
“We are still developing the fire so uniquely, there’s no reason to go look for another match.”
That is an entirely false statement. Mechanical energy sources used by mankind were vastly inferior in quantity and utility in comparison to the chemical energy they subsequently used up to the adoption of fission nuclear energy in the 20th Century. Fusion nuclear energy will be vastly superior in quantity and economy to energy obtained from sources of chemical combustion and fission nuclear energy. Likewise, sources of energy derived from the annihilation of matter and anti-matter will be vastly greater in quantity than nuclear fusion, fission, chemical, and mechanical sources combined. Zero point energy sources derived from the forces which constitute the space-time continuum of the Universe and/or universes would then dwarf all previous known forms of energy sources.
Nuclear fusion energy sources are capable of accomplishing vastly greater levels of energy production and utilization fundamentally impossible to achieve with chemical and solar energy production. One of the many economically revolutionary applications will be the reclamation of elemental chemical feedstocks from garbage and extraction industries and molecular recombination of chemical feedstocks in chemical industries. Another useful application will be detoxification of pharmaceutical, medical, and industrial waste.
