TLDR; nobody are indispensable. Physics would have landed on 
Einstein's theory eventually, maybe he saved it a few decades of 
work. FM synthesis would have been discovered, plenty of computer 
music scientists have a math background and modulating a 
sine-wave with a sine-wave is something you would expect a 
mathematician to do.

So if a genius only can give a few decades of progress, it is 
very difficult to find examples of individual contribution that 
significantly alter technological progress by more than a few 
years.

It is much easier to find example of people who set back 
progress! (e.g. warfare).
