有趣的是，部分消费电子的技术趋势反而在无意间弱化了这类物理泄露的利用空间。 为提升能效，移动芯片不断降低功耗，从物理层面减少了电磁辐射强度，自然也减小了泄露信号。 研究者兼黑客萨米·卡姆卡尔（Samy Kamkar）指出，苹果与Google等大厂的主流硬件在非预期信号方面通常控制得相对较好，他本人虽然曾打造能通过细微表面振动“听”出敲击的激光麦克风装置，但这类能力仍属少数人掌握的特种工具。

With the arrival of automatic lock and reader management with async iterables, dealing with locks from the users point of view became a lot easier.
