As a hardware engineer, I find the idea of security vulnerabilities based on how closely components on a chip are to one another. Most of the hardware implementations we still use aren't really designed to prevent these exploits. Aside from rowhammer, there's also "sidechannel" attacks on shared CPUs, and measuring the electromagnetic fields generated by a PC to reverse-engineer sensitive data. I'm certain that in the future these concerns will play a greater role in how we design computer components and systems. Previously these attacks were infeasible due to the lack of computing power available to sort through what is seemingly just noise.
