>Imagine what possibilities there would be if humanity finds a way to power all its current and future needs that produces no harmful side effects rather than trying to equate science fiction with reality.

So when do we turn off the giant nuclear reactor in the sky we don't understand and might evaporate the planet if something goes wrong?

There is no such thing as 'no harmful side effects'. We can put our head in the sand and pretend that the universe is a friendly place for life and go extinct in the next 100k years or so. Or we can acknowledge that there is no such thing as 'nature' and make the universe fit for us.
