I, for one "believe" that most altcoins have no real use cases.
Wait a minute. Does that imply that the best use case of blockchain tech is as a currency,
The vast majority of computer scientists don't consider a currency the
best use case for blockchain technology.
Currency is (for the moment) considered the
only use case.
or that most altcoins fail to do what they promised to do?
Uhm, yeah, that probably as well, but it doesn't really matter

Really curious, since I'm starting to be unsure with the blockchain hype lately.
And rightly so.
You will probably have heard of "smart contracts" and them being the killer-app for blockchain technology.
That is marketing.
Smart contracts of a wee bit higher complexity than regular Bitcoin transactions may or may not be a valid use case of blockchain technology in the future.
For the moment, there is no empirical evidence for it, though.
It may as well turn out that meaningful smart contracts are too complex for being put to good use "on" a blockchain.
In theory, it all sounds nice and manageable, but there's a whole lot of problems in computer science where theory and empirical evidence clash.
Main reason is probably that we, as humans are, well, stupid.

With the singularity approaching, we'll soon know for sure.
