Nobody is building commercial plants any time soon; it's still in the experimental phase, with new discoveries happening almost every month.

I see it similarly to the difference between a car with a combustion engine and an electric one. Combustion engines are fully developed. We're reaching the maximum possible performance and utilisation. It's a dead end. However, with electric cars, for example, new battery development is far from over. E.g sodium batteries.

And just off the top of my head, in fusion, the discovery of better electromagnets, as happened a while back, can quadruple energy output.It's not a dead end, and writing it off would be short-sighted.

They are building a commercial plant right now, and it will come online in the next 10 years. https://news.mit.edu/2024/commonwealth-fusion-systems-unveil...

Unless I missed something they haven’t even completed their technology demonstrator (planned for 2026). No construction has taken place in 2025.
