I did not watch the video. I assumed the blog post was a transcription since it contains parentheticals like "(audience laughs)".
My takeaway from the transcript was that the author was chaining together webassembly programs like a pipeline in a Unix shell. Is the video about something else entirely?
The post seems indeed a full transcript of the video, and it does mention the everything-is-a-file: "So, going back to where we were with Unix, what does it mean for everything to be a file? What is a file in the first place?"
The talk is fantastic; Xe is a prolific hacker, low-level OS engineer, and engaging speaker. If anyone prefers YT, here's the direct link: https://www.youtube.com/watch?v=QNDvfez6QL0
