I'm not even sure what to make about this comment about shelf life. This is not a dried food product in a box. Development is ongoing and improvements continue to be made. A clear defficiency, for example, are leakages that occur due to no IP network obfuscation at all. That's why we are tracking the i2p developments on their C++ implementation and plan to integrate that ASAP. (BTW, did anyone see that Bitcoin Core recently got the ability to seamlessly run as a Tor hidden service? Nice work by the Bitcoin devs!) These are not perfect solutions of course, and we're all hard at work to make them even better.

No one is promising that any specific technology is the ultimate solution for all time. If they do, grab your wallet and run the other way.
