Hashgraph and how long will blockchain push forward

[Futourist]

Hi everyone.

So this thing called Hashgraph caught my attention recently - it's a completely different and new concept of a distributed ledger.

Here are the key points:
1. Compared to blockchain, hashgraph is better in almost every possible way (energy consuption, speed, security).
2. Hashgraph is just a working concept, there are no public ledgers built on top if it yet (no tokens, sorry)
2. It is not a proof-of-work system and it will never be.
To learn more about hashgraph I suggest reading and watching the presentation at http://www.hashgraph.com.

Here are my questions for you.
In case a better ledger comes along, what do you think will happen to blockchain?
Is there a blockchain lobby that will try to protect the crypto world (bitcoin millionaires) in some way and try to crush other technologies?
Will the blockchain coin & token market crash (and why not) in case Hashgraph developers create a public financial ledger (which probably won't happen for a long time)?

Blockchain is here to stay even after Hashgraph arrives. Yes, Hashgraph will be much better, but both will co-exist for a long time, because some applications just don't need the Hashgraph superior technology. Why will CryptoKitties or Decentraland need the Hashgraph? Blockchain works just as fine.

I'm no expert on the DAG tech used by iota and several others, but this appears to be very similar, using even almost identical graphics to show how consensus is reached.
