In general, I agree with you, but I think that there is a difference between time travel and (e.g.) fusion.

- Time travel as a phenomenon is not known to exist, while fusion is known to exist.

- Fusion experiments are trying to create human-controlled, energy-generating fusion reactions. We know that energy-generating fusion reactions are possible, we just don't know if we can create them under controlled conditions.

- Fusion-generated energy has the possibility to transform that world. Time travel will transform our understanding of the universe, but seems like playing with fire. Were we to discover time travel, we would now have to 'protect time' from 'evil' time travelers.

>>seems like playing with fire

well, fusion is playing with fire (plasma) almost by definition.
