In the South of France, a nation consortium is building a proof of concept "nuclear fusion reactor" that will turn an ounce of seawater into enough electricity to power the planet for a thousand years. Ostensibly the proof is coming in 2025. It's an engineering marvel, including among other things, an electro-magnet that could lift an aircraft carrier.
We've been hearing about "fusion reactors" for decades, but preceding experiments seem to confirm that this , first of a kind thing called a Tokamak, may change the world like nothing before. We seem to have plenty of water from oceans, air from atmosphere and light from sun....so
if a Tokamak or two can give us unlimited electricity, then by definition it will be free, and our spoiled progeny can spend their entire lives just experiencing VR's made by AI's.
