Guess it depends what you mean by technical.
I randomly picked another, "Product fairness testing for developers". It seems to consist of two Googlers reading a codelab out loud. And I mean that literally:

She literally reads out the title, pauses, reads out the subtitle, pauses again, reads out the rest of the document word for word. WTF? Is this person a text-to-speech AI? Why did Google make a video that consists of Googlers doing a TTS-quality video of their own documentation website? I'm a developer, watched many dev oriented tech talks and I've never seen that before.
The bulk of the talk is about how important it is to be ethical and stuff. First time we see code that isn't just a snippet in some docs is at the 22 minute mark in a 34 minute talk. It appears to be little more than running some regexs over some rather incoherent LLM output. The code isn't even explained anywhere, just what it's doing. No dev is going to learn anything from this even if they're at bootcamp level.
The video has got only around 4000 views, which seems about right. I can't imagine anyone watching this and thinking, yes, awesome, let's share it around. BTW the bootcamp level of the code might be because neither of the speakers are developers. One is a product manager, the other is an analyst. Really don't think this is targeted at developers dude despite the title. It definitely wasn't written by one. So that's twice now.
