The technology on that list can be traced back to two scientific breakthroughs. The germ theory, from the 1860s, led to vaccines, antibiotics and surgery. Quantum mechanics, from the 1920s, led to the transistor and the laser. The list ought to mention some chemistry. That came from the atomic theory, around 1800. Once you've been told those ideas, it's a matter of working out details; the details get tricky and progress slows with time. I'm sure there will be another breakthrough on this order. If we're around to see it, no doubt it will come as a complete surprise, like all the others did.

Condoms are another matter. The Romans knew how to make them, and the problem was being allowed to. The solution wasn't a sudden breakthrough, but a hard grind over many centuries. A social breakthrough as powerful as the atomic theory could be amazing.
