“This is not a debate about rejecting technology,” Horvath said in testimony in front of the U.S. Senate Committee on Commerce, Science, and Transportation earlier this year. “It is a question of aligning educational tools with how human learning actually works. Evidence indicates that indiscriminate digital expansion has weakened learning environments rather than strengthened them.”
虽然侧信道窃听听上去近乎科幻，学界与私营机构的实验却多次证实，信息确实会从消费级电子产品中“泄露”。 2015 年，特拉维夫大学的研究人员用不到 300 美元成本搭建了一套无线接收装置，小到可以藏在一块皮塔饼中，却能在数英尺外捕捉笔记本处理器的电磁辐射，从中提取加密相关数据。 另一支团队则展示，只凭普通智能手机麦克风采集电脑电压调节器发出的高频轻微噪音，再通过分析，就有机会推断出加密密钥。 不过这些实验也显示，真实攻击往往需要精心布置的环境和高超技术，获得的信息通常并不完整。
