I'd personally bet on some sort of major breakthrough in space travel or energy sources or both (perhaps due to new physics) to have comparable results to the decades of the atom. Being that, there is just not enough gain or even potential gain of technologies being surveyed right now, even considering full on genetic engineering and universal nanoconstructors. Well, unless immortality or nigh immortality of some form happens. Or we found a way to expand our intelligence and performance in some huge way. And then it becomes available. Compared to atomic and subatomic physics AI is a joke and genetics is at witch doctoring levels. Self driving cars are like the steam experiments in 1800s at best, with even less of an impact. At least genetics has potential to change everything, more than automated transportation ever can. Nanotechnology is making some progress but not nearly fast, good or cheap enough. Another breakthrough could come from side physics like photonics.
