Probably not the next decade. I've seen fusion researchers referred to as "the cathedral builders of our time"—their work will take decades, and they might not see success within the span of their careers, or even lifetimes. But yes, controlled, sustained, repeatable fusion reactions could be a black swan on the order of the internal combustion engine for the 21st century.
