Yes, for example, here's the full quote about voting including the sentence immediately after the one you quoted:

However, to the best of our knowledge, so far no solution has been proposed that has been shown to be secure, verifiable, and private and there are still many open challenges.
There's simply no proposed system which is not worse than the status quo, and that's ignoring the additional challenge that even in the event of a major academic advance you'd have the additional concerns of having to be cost-competitive and establishing public trustworthiness before you could call it better. That kind of work is measured in decades.
The situation is less severe for file storage since you don't have as many attacks but, again, there just isn't something which is comparable on cost, performance, or reliability. I'm comfortable saying that's “known to be worse”.
