There's a lot of HN and YC-aligned people who don't believe this, despite the empirical evidence of the last few decades.
To take the stupidest version of the argument (not going to sugarcoat it, I think it was embarrassingly stupid) there was Marc Andreesen's Techno-Optimist Manifesto where he called for a 1000x increase in energy production from nuclear fission and fusion. I quote directly:
"We believe energy should be in an upward spiral. Energy is the foundational engine of our civilization. The more energy we have, the more people we can have, and the better everyone’s lives can be. We should raise everyone to the energy consumption level we have, then increase our energy 1,000x, then raise everyone else’s energy 1,000x as well."
Driving energy costs to near zero drives down the cost for literally every other process, manufacturing or extractive or services. A 1000x increase in energy practically lets you extract so much material for cheaper that the cost of materials, and the associated logistics, goes down.
