What If Fusion Power Arrived in 2035?

Writing this now, in 2050, fifteen years after that quiet December night in the newsroom, I find myself most struck by how ordinary fusion power has become in the countries that have it, and how urgently its absence is still felt in the countries that don't. My own apartment in Seoul runs on a grid that is now almost forty percent fusion-sourced, a fact I genuinely did not think about from one month to the next until I sat down to write this retrospective.

That ordinariness is, I have come to think, the actual marker of a technology having succeeded rather than merely having been announced. Nobody writes awestruck retrospectives about the extraordinariness of flipping a light switch, a technology that took its own several decades to go from laboratory curiosity to unremarkable infrastructure. Fusion is, fifteen years on, roughly halfway through that same transition: still remarkable enough to merit anniversary journalism, ordinary enough that most people living with it no longer think to be amazed.

I asked Dr. Benali, at the end of our last conversation, what he thought the next fifteen years would look like. He laughed, for the first time in either of our interviews. "I have spent my entire career being wrong about fusion's timeline in both directions," he said. "I was wrong when I thought it would never come. I was wrong about how fast it would spread once it did. I think the only honest answer is that I have no idea, and that not knowing is, after thirty years in this field, the part I have finally learned to find exciting rather than frightening."
