Please don't shoot me 
I too reacted the same way when I read the topic title.Infact,being an optimistic blockchain supporter,I didn't even bother to open the article until the geek inside me pushed me to.Anyway,I was surprised.I mean we should embrace the changes right ? Here ya go,welcome HashGraph.

The new consensus algorithm
Introducing Hashgraph a fair and fast, byzantine fault tolerant consensus algorithm. According to the founding Hashgraph team consisting of computer science and cybersecurity pioneers Dr. Leemon Baird and Mance Harmon, the hashgraph consensus method achieves the following notable feats:
Its fast: 250,000+ transactions per second and limited only by a users bandwidth (Pre-Sharding)
Its fair: mathematically proven fairness (via Consensus Time Stamping)
Its secure: bank-grade security (Asynchronous Byzantine Fault Tolerant)
Why is Hashgraph superior to Blockchain?

The company behind it still undecided. but futrthermore we should be ready at all times. what we have now is blockchain and need to study more about what's on Hashgraph. but still we're on the edge its not too late..
Time will always tell but isn't it pirated from the blockchain? I wouldn't be surprised because there are so many motivated forkers around and should be easily motivated to use one of their ploys to present hashgraph as a new technology or algorithm whinch will rival the blockchain. It's still early days though.
