Lol. That's what I think. They can join the long line of thousands of other "projects" that were going to disrupt an industry. Except that it never happened.
That being said, not very much a game-changer at all, but a nice alternative to the other L2 systems. But it's not going to get anywhere without an ecosystem developed around it. See, the reason why we're all talking about Lightning Network is because lots of people have put in the effort to make clients, wallets, infrastructure, sites, and other programs and protocols for it.
So other L2s would need to put in that legwork as well.
