This is a great point. When I was younger and in college, I took advantage of the fact that I could coast through my engineering classes with the barest minimum effort. So, spent them drinking, playing in a band, and chasing tail. I still graduated in the top 10, but I could have easily done much, much better. Grad school and a couple of jobs later, my philosophy changed, and from somewhere, ambition crept in.
I will say that I have accomplished a lot more with drive and mediocre application of intelligence than with intelligence and little in the way of drive or hard work.
The problem is that you need them both at the right times in your life. Otherwise, it's too late. At a different period of my life, I may have gone through with a PhD and potentially been a physicist if I had had the sense to apply both grit and intelligence.
Today, I am a management consultant, where I use my analytical skills to solve mediocre problems, but where grit and drive and many other soft skills play a role. In fact, I would argue that my intelligence has taken a back seat and I bust ass to make up for gaps in my technical skills (e.g., finance).
Sadly, I am well past the point of publishing seminal papers; but at least, I can make the best of what I have and make a boatload of money for my next generation. But you're right -- it's not coming first. It's not even coming third. It's somewhere around fifth to the tenth. Above average, if you will, but definitely not great.
