More like decades. The earliest time any planned fusion reactor will make net electrical output -- but not yet an economically useful amount -- is the mid 2030s, a decade from now.

Commercially relevant amounts of electrical generation is uncertain, but most plans start around 2045 and then would take decades to replace fossil fuel plants at scale.
