Ethereum has started to see many actual use cases in real life. For instance, major companies like Amazon, Microsoft, Google, Visa are all starting to adopt Ethereum as part of their real life usage.
Ethereum has started to appear in education as well. Duke University (one of the top universites in the USA), has started teaching modules of “Ethereum and Smart Contracts” as part of the syllabus.
Course description (Ethereum and Smart Contracts course in Duke University):
“Learn how to develop smart contracts and decentralized applications on the Ethereum Blockchain as well as history and trends of Ethereum itself. Ethereum is the most promising decentralized smart contract platform, and blockchain developers are in high demand. Learning these skills will give you a leg up in the blockchain world, especially in the Ethereum ecosystem. We will cover Ethereum (the platform), Solidity (the programming language), Truffle (the developer framework), and web3.js (the front-end library). Preference: some blockchain/cryptocurrency understanding. Prerequisite: basic programming skills.”

Ethereum Book
Learning blockchain technology should be a very marketable skill in the near future. Currently, there are two main ways to learn it, through online courses or through books.
Mastering Ethereum: Building Smart Contracts and DApps
The book above is authored by Dr Gavin Wood, who was the creator of the Solidity language and cofounder of Ethereum.
