Ah, the so called Fusion Constant.

I've seen a road map at the start of iter which was actually more. 30 years to get a stable exo energetic plasma, then 30 years to build a demonstrator able to produce electricity, and then 30 years to have industrialised fusion plant.

Essentially yes, https://en.wikipedia.org/wiki/Fusion_power#2020s

https://www.world-nuclear-news.org/articles/helion-begins-work-on-fusion-power-plant One of the commercial entities did start building a plant last year, not particularly large (only 50 MW) with an agreement to power a Microsoft datacenter, and billions in funding from government and private sources.

Hard to tell for real though because the level of secrecy around this is insanity and the US Military is heavily involved in not just this, but pretty much every similar organization.

I would not be surprised if we hear nothing, or see them "failing", even if some of these designs are fully functional already.
