Honestly, I don't really care about that. Yes it uses quantum-sensitive protocols like AES but honestly, who with a quantum computer is either going to:

• Record all my traffic to decode it 10 years later, knowing they will also have to break SSL on top of that!
• Already has a quantum computer or a huge datacenter for paralellisation right now meaning they are the NSA and if they wanna spy on me they are going to anyway. And really if someone has such a datacenter they will use it for AI which is more profitable.

For my threat model the threat of my VPN crypto being broken just isn't important right now especially in my VPN usecase which is already low-importance stuff. There's nothing valuable or personal in that traffic. The only reason I use the VPN is to do torrents really. If they want to grab a few torrenters and make an example out of them it's much easier to grab a few that are not using any VPN. There's still loads of people torrenting directly on their bare home IP.

It's like the saying of the two guys running from the bear. One says to the other: "We're not gonna outrun him!". The other says: "Doesn't matter, I only have to outrun you". Not being the easiest catchable is enough protection.
