For the past few months I've been working on making YouTube videos about space and related ethical concepts (longtermism fits here quite neatly) aimed mostly at a general audience, but folks here may find them interesting too.

Most recently, I made a video summarising some of Robin Hanson's views on economic growth, particularly his 2009 'Limits to growth' post.

The two most interesting things I learned while making this video are:

• Current growth rates of GDP and electricity production will hit physical limits within a few thousand years at most due to physical limits.
• Only 2.6% of economic growth is due to natural resource extraction.

Two other videos that I suspect may be of interest are: 

Will the future be utopian or dystopian? (using sci-fi concepts to discuss the cosmic endowment argument)

Is this AI-brain hybrid sentient? (discussion of digital minds/artificial sentience with recent brain organoid news as a hook)

I welcome any feedback or ideas for other topics to cover! I'm also interested in exploring more interview style content with experts.
