I created a collection of very good YouTube videos about the simulation hypothesis. If you have time for only one, watch the first one here. However, I would recommend watching all of these videos over time.
Here are interesting interviews including Elon Musk and Neil DeGrasse Tyson. Other interesting interviews are also featured.
In December 2021, Neil DeGrasse Tyson interviewed Nick Bostrom.
Other interesting videos
Here are videos that do not necessarily talk about the simulation hypothesis in detail but are good to view since they add more information and perspectives.
This video (about 50 minutes long) gives a good overview of the simulation hypothesis.
Video that give counter arguments
In this video, many arguments against the simulation theory are discussed. Personally, I disagree with the probability method the speaker uses as an argument against the simulation hypothesis. However, the video is well made overall and it is worth watching.
