In reality, commercially viable nuclear fusion is only infinitesimally closer than it was back in the 1980s when a contained fusion reaction — i.e. not occurring in the sun or from a bomb — was first achieved. A meaningfully just energy transition needs to both be fully renewable, and also reject the myths of perpetual growth that emerged from the fossil fuel era. If the end of the fossil fuel era portends the end of capitalist growth in all its forms, it is clear that all of life on earth will ultimately be the beneficiary.
