There are channels without propaganda like ScienceClic/pbs space time. Good propoganda would not work if it would be too obvious. But once you read Kurtz story and try to reevaluate their "proposed" solutions to eco issues, you can see how it aligns. It is "technooptimism". Like similar to "invest into AI, it will solve all of our problems".

Sadly... Ok ok, so it is basically science video channel with sponsored content where they don't say it is sponsored content. Better description?

They offer educational content. From limited consumption I would not rate it as high quality. More like acceptable I guess.
