I agree. Most of us have little worry about a bad piece of software probing 
kernel space and grabbing a few bytes at a time. In any case, all 3 major 
operating systems will soon have patches to fix Meltdown, which only affects 
Intel CPUs. Just keep your system updated. The Spectre exploit affects Intel, 
AMD, and ARM processors. Existing silicon cannot be fixed; however, reading 
out-of-bounds memory using this exploit is very slow, and again our systems 
hardly run random untrusted software.
