Yeah, that's true. I know you're right it's just a bummer. Doing it for real doesn't make sense in the context of today's real-world constraints - it would just be a symbolic move in the sense that in a true "world of tomorrow" fusion reactors would be commonplace, and there'd be no reason not to have one. Like the fusion reactor on the DeLorean in Back to the Future II - just an ordinary piece of future life, no more remarkable than a car or a refrigerator. I think your (quite valid) perspective reflects the difference of the view on risk in Walt's day vs today. When he was setting the vision it was considered worth the risk to fly a real jetpack over the park. Today it's "too risky" even though actual jetpacks are much safer than they used to be.
