Disproving big conjectures can be useful to mathematicans because it means they don’t have to waste time proving results that assume that conjecture.

Sometimes the very attempt to disprove a conjecture will produce new insights along the way. To get comparable value when a machine simply spits a counterexample, you'd need to at least mine the intermediate reasoning traces to see its false starts.
