These problems stem from speculative execution. The complete solution is to do away with it entirely, crippling CPU performance. Personally, I don't care about these issues, because they're extremely difficult to exploit, and with a modicum of care for security, consumers have nothing to fear. Servers and other exposed business systems are a different proposition, though.

I'm more angry that brain-trust-level research at universities ends up in published methods to make life easier for hackers. What are the odds these vulnerabilities would have ever come to light without it? Nothing is completely secure. Why go through all that effort to expose the holes for everyone to see? Keep that stuff secret from the public; tell only the CPU makers, so they can spend whatever time it takes to patch and redesign without making the bad guys so much wiser.
