Many badly needed goals, like fusion and cancer cure, would be achieved much sooner if we invested more.

I would like nuclear fusion to become a practical power source. It would provide an inexhaustible supply of energy, without pollution or global warming.

I have wanted to fly into space for many years, but never imagined it would really be feasible.

Science can lift people out of poverty and cure disease. That, in turn, will reduce civil unrest.

It maybe not to cure, but at least (it can have) an effect on patients with cancer.

If aliens visit us, the outcome would be much as when Columbus landed in America, which didn't turn out well for the Native Americans.
