Five years is fantasy—no one has even built a demo plant yet. Engineering, regulation, and supply chains take decades. 10-20 years is the realistic window.
Fusion is finally moving fast, but grid-ready plants need years of engineering, regulation, and scaling. Five years is hype; 10–20 is the real window.
Five years is absolute sci-fi delusion. The physics works, but building the massive infrastructure to actually power the grid will take a solid 15 years.
Fusion breakthroughs are real but scaling to reliable grid power takes serious engineering. Expect it in 10-20 years, not tomorrow.
