Ark tries to solve a couple of things for easier integration of blockchain. If it's the future of money is too early to tell. And there are many to claim exactly that.
But very few who have (1) a working product, (2) constant updates on both the software and general community updates, (3) conferences, some of them educational, sponsoring events and generally a good marketing team.
The only issue I see is that some alternatives came at a better timing and "grabbed" the attention of people before ARK started.
