Personally I despise the currency aspect and 'get-rich-quick' types that plague the space. However, not everyone is into blockchain tech for those reasons. I personally I got into Bitcoin and later Ethereum due to what happened to wikileaks.org A few calls from a senator and the domain was taken away and amazon shutdown their servers. I have been fascinated ever since on how to create an internet in which this sort of censorship is nearly impossible, and while Ethereum is not quite there, it's making progress torwards it, specially the upcoming release of its domain system and decentralized storage.
