Okay I'll explain myself using the link

It has been conjectured that the reason why people older than zoomers[d] tend to include a pause at the start of their videos is to make sure that the device they are using is actually recording before beginning to say anything.[1][23] In contrast, younger users are said to trust that the devices are working correctly, and begin speaking immediately after the recording begins.[1]

Another theory for the pause's prevalence is that the habit may have first been adopted when earlier recording devices commonly took a split second before beginning to record.[24] Although newer devices do not exhibit the same delay, this habit has proven hard to break.[24]

its those two things

so, zoomer, explain why you trust these devices that the NSA is using to spy on you
