I've been following this project for a while now and I truly believe the lead developer Ohad Asor is on a completely different level than any other expert I've come across. The word genius is tossed around very loosely in the tech industry, especially in the crypto space, but that man is something else entirely.

To the extent that I can follow his vision, I'm very impressed by it. And I believe he's one of the very few people on the planet who has the ability to implement this vision.

Tau is definitely worth having on your radar as it may prove to be an indispensable technology one day.

But don't take my word for it, ask him some difficult technical questions in maths, logic, cs, programming, crytpo yourself in his irc  and judge him for yourself.
