I remember when I thought nuclear fusion was the key to interstellar space travel because tech science channels hyped it up like that.

Now that I understand the science from real scientists, nuclear fusion is like the least space efficient form of energy production and isn't going to fly us anywhere or even be used to produce energy at all, because the whole point is that it happens incredibly slowly to not burn out stars immediately, and the human body outputs like 100* more energy in heat than the sun does for the same amount of space.

So, uuhh, maybe we have made a lot of optimistic assumptions about the short term future of space travel
