Current state of software is only appropriate for some use cases. Email/text messaging (like 4chan) are not practical uses. Financial business logic handling is a great use case.
Financial business logic is not a great use case, approximately no one uses it for that. Almost all of the interest in BTC/ETH is driven by speculation and greed, which is a shame as it's a whole new computing paradigm.
Good use cases exist because of the viability of the platform, not of their popularity. And even I meant to communicate financial "business logic", which is widely used in ICO's.
Speculation and greed is the foundation of all new technology.

I do not see greed anywhere in this exchange. Also there's a difference between what people normally describe as investment vs speculation. The first being assuming a growth of value of something useful. The second is making money on the difference in a value, completely ignoring what the value represents. (yeah, the line is a bit fuzzy in practice)
