I keep hearing he's retired, yet his channel looks just like any channel by a full-time influencer. The few videos of him I've watched (all quite recent) must have required substantial effort. Like, he's showing off extensive Linux ricing, complex UI/orchestration tools for LLMs,... on top of refined video editing. Whoever actually made all of that, that must have required non-negligible resources. Probably a lot more than videos in his older style, which were more like stream recordings. The cadence of his videos also seemed comparable to other channels I follow. And his videos were all monetized hard, through YouTube, in-video sponsorships, and even in the video description he was selling his subscription newsletter. To me this seems more like he's still very much in the business of selling online content and just evolved his style.
tl;dr: I don't think you and I have the same meaning associated with the word 'retired'.
Moved on from content for kids, now retired peacefully in Japan.
There was that odd moment where he was competing for subs with T-Series, the Bollywood music company, but when he realized he wouldn't be number 1 on YouTube forever, he just stopped giving a shit.
