This statement ignores a ton of other factors, and provides a particularly poor example. What did Einstein do to alleviate hunger? Most of his contributions remain theoretical or applied to things that don't directly help the population (or haven't paid off yet).
Even if you have someone who is intelligent, will their contributions actually make life better for people? Or will their ideas become commercially corrupted and be used for greed (Edison commercialization vs Tesla gifting)? Will they complicate our lives or provide harm along with some benefit (social media, TV, etc)? At such a small rate of the population (using your 1/1 billion), would a truly good idea gain traction? Maybe the idea to eliminate or restrict meat is theoretically a good one. But are you going to convince all the people to support it? Then how much impact will it actually have?
There is no magic solution nor hyper intelligent person that will save us.
But has it helped with living conditions like food and shelter? Sure it's made life easier, even for stuff like tractor positioning for field planting. But I don't see it having a real impact on those sorts of issues. I guess it has made many munitions more accurate and reduced collateral damage.
Have you tried moving through a desert or a steppe in the dead of night, far from human infrastructure? It's damn dark, the land is literally darker than the star-strewn sky. Headlights give you only so much light, for the next 100-150m of the road maximum. Unless it's a really nice, well-maintained road, with reflector posts, etc (and usually it's not), it's really easy to lose your way if you drive a tad too fast. You either crawl, or choose to camp and wait until the morning light.
With a GPS map, you can proceed much more confidently. And a few hours may play a serious role in disaster relief.
So too can the stars, or proper time/speed/direction navigation.
I'm not saying GPS isn't useful. I'm saying it hasn't had a life changing impact for the masses that allows for a larger population (eg it's not providing more food, shelter, etc).
