My science-fiction addled brain can't help but be taken to things like anti-gravity when we start talking about understanding the particle the causes mass. If we could alter the field, we could make things much less massive, making Michael J Fox's hover board that much closer to a reality.
Of course, this is baseless conjecture and, even if true someday, will be nothing like immediate. However, without understanding the field, we won't be able to affect the field (we may never be able to affect the field when we do understand it).
