Don't worry, once China surpasses the rest of the world in technology we can hack them back and steal tech to upgrade our military. The circle of life. Why spend billions on R&D when a couple guys in a basement can get it for a couple thousand $ in computer parts.
I bet that only a small portion of hacking has been uncovered. The majority is still going on undetected. Even if the computer systems were completely fool proof. Employees can still be bribed or black mailed to leak info like the good old days.
Just accept and/or ignore it and get a good nights sleep.
When you do things right, people won't be sure you've done anything at all.
