Yes, but those new discoveries are less fundamental.
One of the reasons we had such an explosion of new theoretical physics in the first half of the 20th century (which gave birth to all the practical discoveries you mentioned) is that, in 1900, there was just so much unexplained weird shit.
Shit like:
1. How do you predict the energy of electrons produced by shining light on a surface? And why does light cause electrons to be produced?
2. Why is the speed of light the same in every direction, to really, really high precision?
3. Why are there spectral bands in the light from stars? And why are they sometimes shifted?
4. Why can current pass only one way through a metal pin poking a semi-insulator?
5. Why does pollen appear to move randomly in the sunlight in still air?
6. Why the fuck is the sky blue? Why does light sometimes act like a way, but sometimes like a particle?
Remember, a lot of this weird shit went unexplained for 25-50-100 years. Then, between 1900 and 1950, smart people came up with theories that explained all the weird shit. So we don't really have so much weird shit anymore because most of it has been explained. Sure, super-conductors are kinda weird, but we also seem to be able to predict a lot of their properties from existing theory.
So, we're really just riding the coat-tails of scientists from 100 years ago. People 100 years from now aren't going to have coat tails to ride.
