I think the bigger problem is that too many people are focused on short term things like personal wealth or glory.
The guy who make the breakthrough that enables the AGI that destroys humanity will probably win the Nobel Prize. That potential Nobel probably looms larger in his mind than any doubts that his achievement is actually a bad thing.
They guy who employs that guy or productionizes his idea will become a mega-billionaire. That potential wealth and power probably looms larger in his mind than any doubts, too.
