Very true, and wise, in this market especially skepticism is the aim of the game!
I think it's important to keep a level head in terms of disruptive potential for all these ventures into new arenas for blockchain, but also to recognise potential on different levels. In the cae of Jur, it's not going to replace the traditional legal system, but it might alleviate some of the problems leading to legal proceedings in the first place. I can definitely see how it would provide a more accessible alternative for parties to be able to enter into confidently secure agreements rather than needing to rely on traditional structures.
That said, adoption is KEY- you can't have a community-powered platform without the community, and right now that's one of the biggest challenges for new project so will be one of the toughest hurdles in my opinion. This market is not kind to newcomers right now!
