This is ridiculous. We’re seeing innovation EVERYWHERE, and looking back, this will be a golden age for progress (if the species makes it far enough to look back, that is). Think of it like this: we invented personal computers. At the time, only nerds had access to computation. These days, all kinds of scientists just script up things in python. We have how many million people who are able to code? I don’t even care…
So, I basically agree with you that there's lots of progress to be amazed by. I also think that the "genius" model is fundamentally flawed, at least in today's age -- there's something to be said for the possibility that education and support systems have improved to the point where maybe geniuses are everywhere. If anything I think we have too much of a genius mythology, and maybe this paper is sort of inadvertently…
1. Even if everything now is mostly engineering rather than science, the difficulty in such feats has to be taken into consideration. Anything from a nuclear bomb to the Moon landing was much more interesting from an engineering rather than a scientific perspective. So, perhaps we have directed our geniuses to implementing change in the world, rather than writing essays or doing other abstract work.
2. To go from 1985 desktop computers to modern phones, a lot of scientific work had to be done. To pick one example, the AI research we are developing in order to perform face recognition, semantic search, translation, and so on is simply revolutionary. Just because we cannot pinpoint a single genius behind any of these achievements, we should not underestimate how significant they were.
