With all the computing power they do have and will have they could, in
theory, try to break the CA certificates themselves. They can collect
and store the encrypted traffic and then at any time decrypt said
traffic when they've done breaking the CA certificate used to encrypt
it. It could be worth it for them in case of the big CAs.

For all we know, the big CAs could have received secret court orders
where they are required to hand over the certificates themselves,
foregoing the aforementioned step.

This incertainty due to this kind of secrecy isn't good for the mind.
