IPFS has a ton of potential behind it, as it makes publishing, accessing and retaining content drastically easier than HTTP. The content-addressing also means you can basically sidesteps the whole act of "downloading", no more need to download a file, extract a file, etc. You just access it directly in your file system by a unique name.

That said, I am also very pessimistic on it. IPFS suffer from "underspecification". The protocol is completely focused on just moving bytes around. It doesn't care about copyright or authorship, which becomes a huge problem due to content no longer having a real home in IPFS, everybody can pin, cache or share content on IPFS. It's very much like Bittorrent in this regard, but worse as even Open Source licenses don't help here. IPFS, unlike Bittorrent, doesn't even guarantee that content will stay together, e.g. you can pin and reshare your favorite icon, without a hint of what license it is under or what icon theme you picked it from. For the time being everybody seems to just ignore the problem, but I think it will kill it if it gets popular before this problem is solved.

Another problem is that it's just buggy and slow, especially when it comes to the fuse daemon that provides the /ipfs and /ipns directories. Though that at least is fixable on the client side. The copyright problem might not without some fundamental changes to the protocol itself.
