Unfortunately we are not even close to getting control of fusion just like fission. And for fission, we can hardly tell whether it brings more benefit than harm as the radioactive wastes take so long to neutralize.
We can achieve fusion already, so presumably we already have control of it? Check out lppfusion. https://lppfusion.com/technology/focus-fusion/
I think if we discarded the failed attempts we could consolidate something here.
