Yes, there's tons of hype, nonsense and even scams, but the cream will eventually rise to the top, and the best ideas will survive. I've listened recently to some podcasts with Olaf Carlson-Wee, someone who has thought long and deep about the implications of having funding at the protocol-level of the internet, and how it could swing the balance away from large, centralised web monopolies who capture most of the value, towards the users of the network[1]. Union Square ventures also have some interesting ideas as to where the future of the internet might be heading.[2]
It's hard to see where we're heading with all the short term price boom and busts though, which I agree are unconnected with reality (currently).
