Edit: thinking of other technology adoption curves. Faster than EVs but slower than web and mobile. Thinking of finance too. What's the adoption of NFCs/touchless payments/chips look like? What about the rise of microlending/lending club etc?
Ethereum came along in 2015 and introduced the concept of the Ethereum Virtual Machine and smart contracts. Now "blockchain" is a bona fide platform where people can leverage Ethereum and the underlying blockchain network to build things. Another question - why did it take six years for blockchain technology to progress from digital cash to platform?
Now seven years after that even when combining digital cash (payments), "store of value"/gambling (trading, speculation), and all things smart contract (NFTs, DAO, ENS, microlending, etc) there are still at best 100 million total users for all of these use cases combined.
