Blockchain is often accused of being a technology looking for a problem. As if this Tech Pull effect is something to be avoided at all costs. I think innovation and progress is always a balance between Tech Push on one side and Tech Pull on the other. Sometimes the market is looking to have a problem solved, sometimes technology can solve a problem you didn’t know existed. And both are always evolving and in motion.
A few successful examples of Tech Push are the car (Tech Pull would have led to faster horses) and the ever popular example of the iPhone/iPad. The trick is to strike a good balance between the two. Harder to do, but ever the more interesting to be working on.
