the point here is: the propability that a quantum computer will arrive
in 10-15 years time is not zero. It might not happen, but maybe it might.
So if you have communication that is important enough that you do NOT
want the NSA to read it in 15 years from now, you can not use classic
diffie-hellmann for key exchange - because it will be broken, and then
all your sniffed-and-saved-for-breaking-later communication will be
out in the clear.
If you use OpenVPN to securely access remote networks, and do not care
about anyone decrypting the stuff a week later - nothing to worry, for
many years to come.
But do not dismiss the wisdom of people better at math than you (and I).
