I am a .net application developer with 5 years of experience.

Several modern solutions are being created by using IOT to collect data, use machine learning to perform analysis and have a blockchain in the backend. The web or mobile application is only a part of such a solution. I may not be able to understand or design a modern solution without having knowledge in areas beyond .net application development.

So, to what extent should one should acquire knowledge of blockchain, iot and machine learning to rise in the IT industry.
