Specifically, that upward leap in the growth of the productive forces that would result from the implementation of Hydrogen-Boron, direct-conversion, radioactivity-less nuclear fusion electricity generators; economical, sea-coast fusion-desalination/irrigation/ocean-solution-mining plants; elemental "fusion-torch" recycling plants, etc., is ESSENTIAL to a transition to a communist, or political-economic-democratic, society; to enabling a DECENT standard of living for the majority of the human species — not to supply a decadent capitalist hyper-consumerism to all, which they do not want, or need, but to produce the basic necessities of a humane material life — by and for a majority of humanity which now suffers under the most abject and dehumanizing privation.
In general, the growth of the human-social forces of production — of the life-creative, human-wealth-creative, self-powers of the human social individual, and of the human-social totality, within the rest of nature, as an outgrowth of nature, and as [the 'meristemal'] part of nature — is the primary project of human liberation.
This project cannot be a conscious, deliberate collective project within the entire span of "human prehistory" [Marx], which prehistory only ends with the emergence of humanity from its capital-value-form. Before that emergence, this project is part of the "cunning" of the collective species-unconscious. Specifically, under the capital-value-form, it is not pursued, collectively, consciously as such, but only indirectly, in the form of the pursuit of transitory "super-profit" opportunities by the personifications of the capital-relation, via the increase of labor productivity to reduce the unit cost of commodity output, which, upon deeper analysis, is revealed as the pursuit of rising rates of relative surplus-value.
For individuals outside the class of capital-personification, the development of "technology", and the choice of "technology", appears as alien, as an affair of capital and its engineering, etc., employees, from which the wage-working population is excluded, or it even appears, to impressionistic empiricists, in an illusory manner, as an autonomous development, outside of any human control.
"Technology" develops as fixed capital — as an objectification and materialization of THE CAPITAL-RELATION itself; "technology as capital"; "capital as a technology" — and therefore in a manner which is disfigured, deformed, and perverted with respect to the designs of a communist political-ECONOMIC DEMOCRACY, aiming at the production of SOCIAL use-value/SOCIAL negentropy.
Only within an emergent post-capitalist, post-pre-historic, communist society — a political-ECONOMIC DEMOCRACY — can the expansion of humanity's self-expansive, self-creative, self-reproductive powers become a conscious project — a matter of democratic deliberation and of collective-conscious design.
The development of the human social forces of human society [[self-]re-]production organizes itself into epochs — which only complexly correspond to the epochs of the human-social relations of production — and which epochs each center upon the accession to, and the appropriation of, deeper, earlier-to-emerge layers of nature by the human species, in the form of the different, successive epochs of ENERGY [re-]SOURCES. This progression of energy [re]sources appropriation by humanity takes the form of an inverse recapitulation of the dialectic of nature — of a reverse revisitation of the self-progression of the levels of self-organization of nature.
Thus, the human appropriation of nature progresses, cumulatively and inclusively, from the appropriation of human-social energy [collective labor, as in coordinated group hunting], to the appropriation of animal-social energy [e.g., herding, and, later, animal domestication], to that of the [eukaryotic] multicellular energy of human and animal bodies in labor [as in the "harnessing", or "yoking" of horse-body — and of human-body — to plow], to that of eukaryotic-cellular energy [e.g., composting, leather tanning, yeast-based "daily bread"; other food production and preservation via bacterial fermentation — chocolates, buttermilks, sour creams, sauerkrauts, yogurts, kefirs, beers, wines, pickles, vinegars, tofus, etc.], and, later, to that of prokaryotic-cellular energy [e.g., sewage processing — sewage treatment ponds, septic tanks — etc; later [hybrids]: methane digesters; antibiotics-production and other medicines-production via "biotechnology", petroleum spill digestion, metal prospecting and mining, etc.], to that of molecular energy [of chemically-bonded atoms' electron outer-orbitals; via Oxygen-combustion of organic and inorganic chemical structures — deceased plant matter ["wood", etc.], cow chips, peats, coals, mineral oils, natural gases, etc.], to that of atomic-nucleus power [nuclear fission; nuclear fusion, or ionized-Hydrogen/protonic power, thus on the borderline with "sub-atomic power"], and [predictively] on to that of sub-atomic energy, thence on to that of sub-nuclear energy, etc.
Please note that the concept of '''energy''' invoked above is not the reductionist concept of "energy" common in modern science, but a non-reductionist concept of '''energy''', '''negentropy''', or '''organization-maintaining/expanding activity''', which acknowledges the ontological differences distinguishing the 'auto-kinetic' propensities of the different, successive, nested, '''natural-history historically-specific''', and «aufheben»-related layers of natural self-formation, and the qualitatively differing consequences thereof.
Given this principle and pattern of progression of the energy-basis, and nature-appropriation-deepening basis, of the growth of the human social-reproductive forces, fusion — that is, nucleus/sub-atomic energy appropriation — is the expected/predicted next accomplishment in the productive-forces/energy resources progress of humankind.

If you listen to it through to the end, you will hear some amazing revelations about just how held-back technological progress has been since the 1930s.
