Don't have any illusions, blockchain is not widely adopted and used in production, with the recent stackoverflow developer survey results showing that more than 80% developers say that they don't use blockchain and a high amount of developers are skeptical about its future. The article just lists startups that promise to do something with blockchain, but show me how many of those startups have turned into successful and recognized companies.
It's true, blockchain is still not widely used because of various reasons but I think this will change. There are a lot of industries where it could be implemented like finances, healthcare, agriculture and similar and many governments are also interested to see implementaion of blockchain. That is why regulation is changing, some national plans and strategies are being developed, at least in Europe, as far as I know.
