(I'm continuing my thread from May 2014.)

I have been reading through this thread.

Most of you don't seem worried about the possibility of 4096 qubits
happening (i.e., of RSA-2048 being cracked) at all before you are dead.

But what about younger people here in their teens, 20s or 30s? What am I

* Is there simply no general interest to address this at this time in the
cryptographic/PGP community?
* Maybe I should ask again in 10 years? If people notice that Moore's Law
is holding up for qubits after 10 years, maybe they'll more eagerly start
looking for solutions?

Right now my main worry is that people will store a lot of encrypted data
long-term and crack it open in 50-60 years using a quantum computer.
Because of this, every time I use PGP I have to ask myself: Do I care if
people crack this after 50 years? It's cumbersome.
