At active fusion temperatures, IIRC, about 27 million degrees Fahrenheit, I don't know how they'd contain it if it were on a scale large enough to do useful work.

I'd say there are some practical issues to be resolved before they'll have fusion on line at a commercial scale.

Why let that hold us back? In countries like China, India, and vast parts of Africa, where there is no distribution infrastructure in place, or in Afghanistan or parts of Pakistant, so remote that, even if they started on it today, it would be two to three decades before distribution infrastructure sufficient to provide power to were in place. OTOH, they could build off-grid housing there, particularly since the demand for "conveniences" is not yet present, and meet much of their citizens' needs.
