From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Isn't elliptic curves cryptography sensitive to quantum computers attack? Shor's algorithm etc
Yes, it is. ed25519 depends upon discrete log for its security, which Shor's algorithm can (theoretically, of course, not like it's ever been done) efficiently solve.
The post-quantum algorithms are in active research right now. I don't blame anyone for avoiding those at least until we've quantum computers big enough to solve baby toy elliptic curves.
Yes, though OpenSSH has already switched to a quantum resistant algorithm for key exchange (Streamlined NTRU Prime, combined with x25519 in case SNTRUPrime turns out to be weak), and that's the stuff that needs to be switched as soon as possible to preserve forward secrecy. Authentication keys are less urgent.
