Perhaps the oldest and most storied genre of entrant in this list, MIDI foot pedals have existed in some form or another since the final days of the hair metal era. A traditional setup involves a rack mounted switcher, which has five or more loops in which a guitar tech would place an analog pedal like a Tube Screamer or a Big Muff. The rack lurks in the shadows of the stage behind the wall of amps, untouched by the guitarist. Said guitarist then stomps on a foot controller up front to send MIDI Program Change (PC) messages to the switcher, telling it which loops to engage and disengage. One button enables or disables an infinite number of effects, making it much easier to focus on more important tasks like playing guitar, chugging Jack Daniels, or glaring menacingly at your guitar tech.

李燕锋：有一部分是形同虚设。比如青少年模式，一是适配青少年的优质内容供给严重不足，二是你在这个平台限制我玩20分钟、30分钟，那我换个平台不就行了？或者换张卡、用家长身份绕开。短视频也一样。再加上算法推荐机制具有“成瘾性”，精准推送不断强化用户黏性，让青少年深陷“信息茧房”难以自拔。
