Hacking [breaking boundaries, making the seemingly impossible possible by pure force of will] is the archetypal example of this. Obviously, the discipline is not new and has been present for thousands of years, any sort of artistic/creative process encapsulates it.
The arrival of cyberspace however and its subsumption of more and more aspects of our everyday lives acts as a positive feedback loop. What was unthinkable or even heretical 20-30 years ago is now routine.
In a sense, we are witnessing a new paradigm shift where the intermediate substrates (mind/inception to manifestation) are being dissolved and the feedback loop gets shorter.

You can see this with the subsequent breakdown of social structure and monetary philosophy. The masses are reaching harmonization through their own voices rather than having a conductor leading them (politician/bankers/middlemen in general)
What would be an example of this?
Are you referring to something similar to multiple discovery:
