I like being optimistic, but there is nothing to be optimistic about when it comes to producing electrical power from laser ICF. It's a weapons program.

Also, I spent a few years as an engineer at a stellarator. This video[0] recently came out and I find it's the best crash course on the nuances of reactor design that I've seen. It really nails the thoughts and feelings of fusion researchers. It was especially refreshing to hear in public that ECRH is the only viable heating method for a reactor.

If you watch this you might think I'm pessimistic about fusion, but I'm not. Fusion has been sold as this secret Ace up our sleeve that will come in and decarbonize our grid in a matter of decades. It isn't that. That's what's been sold because it's difficult to justify the field when the timelines don't decarbonize the grid in 50 years. The important thing to know is that the world doesn't end in 50 years. Energy demands are ever increasing and the supply is ever diminishing. Fusion science is expensive and time consuming. Humans will have to do the work if they want to stay on the current track beyond the next 100 years. It might seem like a subtle point and a doomed one to make considering how shortsighted we as a society have demonstrated to be.
