Just realized my 4-year-old has been watching TikToks on my iPad

Cool cool cool. So I found out yesterday that my son figured out how to get to TikTok on my iPad and has been watching god knows what for the past week while I thought he was watching Bluey. He was watching some guy do parkour stunts and apparently decided to try it off our deck. Not a huge fall, thank God, and no injuries, but now I'm the worst parent alive and my wife won't stop giving me the silent treatment.

Anyone else have a kid learn technology way too fast? How do you actually manage this stuff without feeling like a failure?
