Future of Nuclear Fusion

I was watching a YouTube video about the possibility of nuclear fusion as a power source in the future.

A few days ago I shared a video in a post about nuclear fusion being used in commercial power plants, if it ever happens, being decades in the future due to the numorous technical and engineering issues. Maybe that's the way it is supposed to be. As the video shows most of the fuel for a fusion tractor can be abundantly gathered from the outer solar system's gas giants. We're also decades away from routinely sending spacecraft that far into space. When we're ready to colonize the solar system we'll probably have worked out reliable fusion reactors.
