How can u say that? The man is working on the project days and nights and weekends. There are almost daily updates on the irc channel. Interesting things are on the way.
Tau is quite a complex creature so summarizing it into a whitepaper is quite challenging task - I believe that in this phase Ohad can write a hefty book on the world of tau. I'm not familiar with all the projects in the blockchain landscape but from what I know this is the most ambitious project by far. It is also a mistake to characterize tau by its blockchain only because this is one layer of tau which should enable the more advanced features and the economy on top of tau (agoras).
A few videos/interviews are in the pipeline and they will give a better understanding of tau in the near future.
I urge people who want to learn more about tau to join the irc channel and go down the rabbit hole.
Here in the forum it is mostly around the economical value of tau (at least in the last months), nothing wrong about that - this project couldn't go forward without people investing money with the belief that it will give them nice returns in the future. I also believe in the huge financial potential of tau, but it is insignificant compared to the game changing technology that is created and implemented by Ohad - we are talking about a revolution which can be compared to the internet revolution - something that can change humanity.
We have a chance to sit in the front row on the journey to Mars - don't underestimate it.
