I feel like the general tendency on HN (and my personal feeling about the subject) is one of interest in the tech and applications, but a feeling that the hype is bigger than the truth.

The ideas that Ethereum is innovative, that there are lots of possibilities in cryptocurrencies/blockchain, that at the moment the scene has major environmental issues, and that the current high valuations are unjustified, to my mind can all be true at the same time.
