    Both side channels are the result of the chips’ use of speculative execution, a performance optimization that improves speed by predicting the control flow the CPUs should take and following that path, rather than the instruction order in the program.

    Hasn’t this been a problem in other CPUs too? IIRC that’s how Spectre works too.
